st/egl: Set pipe_resource::array_size to 1.

r300g: do not remove unused constants if we are not near the limit

r300g: fix pointer arithmetic with void* in transfer_inline_write

mesa, st/mesa: fix gl_FragCoord with FBOs in Gallium

gl_FragCoord.y needs to be flipped upside down if a FBO is bound.

This fixes:
- piglit/fbo-fragcoord
- https://bugs.freedesktop.org/show_bug.cgi?id=29420

Here I add a new program state STATE_FB_WPOS_Y_TRANSFORM, which is set based
on whether a FBO is bound. The state contains a pair of transformations.
It can be either (XY=identity, ZW=transformY) if a FBO is bound,
or (XY=transformY, ZW=identity) otherwise, where identity = (1, 0),
transformY = (-1, height-1).

A classic driver (or st/mesa) may, based on some other state, choose whether
to use XY or ZW, thus negate the conditional "if (is a FBO bound) ...".
The reason for this is that a Gallium driver is allowed to only support WPOS
relative to either the lower left or the upper left corner, so we must flip
the Y axis accordingly again. (the "invert" parameter in emit_wpos_inversion)

NOTE: This is a candidate for the 7.9 branch.

r300g: implement simple transfer_inline_write for buffers

r600g might need something like that as well. This speeds up constant buffer
upload a bit.

r300g: use internal BO handle for add_buffer and write_reloc

Small perf improvement in ipers.

radeon_drm_get_cs_handle is exactly what this commit tries to avoid
in every write_reloc.

gallivm/llvmpipe: remove lp_build_context::builder

The field was redundant. Use the gallivm->builder value instead.

mesa: replace more MAX_WIDTH stack allocations with heap allocations

r300g: fix build

r300g: Drop unnecessary cast

r300g: Abort if draw_create() fails

The other drivers need to be updated to do this, too.

r600g: bump texture/cb limits appropriately for evergreen

r600c: bump texture limits to hw limits

gallium/util: add states relevant to geometry shaders

mesa: Temporary hack to prevent stack overflow on windows

e.g. st_readpixels is trying to alloca() an huge ammount of memory from
the stack.

wgl: Fix visual's buffer_mask configuration.

mapi: Hack to avoid vgCreateFont being generated as vgCreateFontA.

Right fix is probably stop C-preprocessor abuse and stick 100% with
scripted code generation.

mesa: Add getters for ARB_copy_buffer's attachment points.

Fixes more complaints by oglconform.

mesa: Add getters for the rest of the supported draw buffers.

MAX_DRAW_BUFFERS is 8, so allow all 8 GL_DRAW_BUFFER# to be retrieved.
Fixes complaints by oglconform.

glsl: Fix flipped return of has_value() for array constants.

Fixes glsl-array-uniform.

WIN32_THREADS -> WIN32

Fixes nasty bug where some parts of the code didn't define WIN32_THREADS
and were using the integer mutex implementation, causing even confusion
to the debuggers.

And there is little interest of other thread implemenation on Win32
besides Win32 threads.

softpipe: increase max texture size to 16K

mesa: raise max texture sizes to 16K

This allows 16K x 16K 2D textures, for example, but we don't want to
allow that for 3D textures. The new gl_constants::MaxTextureMBytes
field is used to prevent allocating too large of texture image.
This allows a 16K x 32 x 32 3D texture, for example, but prevents 16K^3.
Drivers can override this limit. The default is currently 1GB.

Apps should use the proxy texture mechanism to determine the actual
max texture size.

r300/compiler: disable the swizzle lowering pass in vertex shaders

It was a no-op because all swizzles are native there.

wgl: Unreference the current framebuffer after the make_current call.

To prevent a dangling pointer dereference.

util: Don't try to use imagehlp on mingw.

util: __builtin_frame_address() doesn't work on mingw.

util: Plug leaks in util_destroy_gen_mipmap.

wgl: Fix double free. Remove dead code.

r300g: fix up cubemap texture offset computation

Broken since 4c7001462607e6e99e474d6271dd481d3f8f201c.

util: C++ safe.

retrace: Some fixes.

st/vega: polygon_array requires a deep free.

A polygon array is an array of pointers to polygons. The polygons
should be freed with the array.

st/vega: Destroy the pipe context with vg_context.

glsl: Fix linker bug in cross_validate_globals()

Cause linking to fail if a global has mismatching invariant qualifiers.

gallium: support for array textures and related changes

resources have a array_size parameter now.
get_tex_surface and tex_surface_destroy have been renamed to create_surface
and surface_destroy and moved to context, similar to sampler views (and
create_surface now uses a template just like create_sampler_view). Surfaces
now really should only be used for rendering. In particular they shouldn't be
used as some kind of 2d abstraction for sharing a texture. offset/layout fields
don't make sense any longer and have been removed, width/height should go too.
surfaces and sampler views now specify a layer range (for texture resources),
layer is either array slice, depth slice or cube face.
pipe_subresource is gone array slices (or cube faces) are now treated the same
as depth slices in transfers etc. (that is, they use the z coord of the
respective functions).

    gallium: rename element_offset/width fields in views to first/last_element

    This is much more consistent with the other fields used there
    (first/last level, first/last layer).
    Actually thinking about removing the ugly union/structs again and
    rename first/last_layer to something even more generic which could also
    be used for buffers (like first/last_member) without inducing headaches.

    gallium: separate depth0 and array_size in the resource itself.

    These fields are still mutually exclusive (since no 3d array textures exist)
    but it ultimately seemed to error-prone to adapt all code accept the new
    meaning of depth0 (drivers stick that into hardware regs, calculate mipmap
    sizes etc.). And it isn't really cleaner anyway.
    So, array textures will have depth0 of 1, but instead use array_size,
    3D textures will continue to use depth0 (and have array_size of 1). Cube
    maps also will use array_size to indicate their 6 faces, but since all drivers
    should just be fine by inferring this themselves from the fact it's a cube map
    as they always used to nothing should break.

    gallium: more interface changes

    In particular to enable usage of buffers in views, and ability to use a
    different pipe_format in pipe_surface.
    Get rid of layout and offset parameter in pipe_surface - the former was
    not used in any (public) code anyway, and the latter should either be computed
    on-demand or driver can use subclass of pipe_surface.
    Also make create_surface() use a template to be more consistent with
    other functions.

    this also changes flush_frontbuffer to use a pipe_resource instead of
    a pipe_surface - pipe_surface is not meant to be (or at least no longer)
    an abstraction for standalone 2d images which get passed around.
    (This has also implications for the non-rendering state-trackers.)

    gallium: fix array texture interface changes bugs, docs

    gallium: interface changes for array textures and related cleanups

    This patch introduces array textures to gallium (note they are not immediately
    usable without the associated changes to the shader side).
    Also, this abandons pipe_subresource in favor of using level and layer
    parameters since the distinction between several faces (which was part of
    pipe_subresource for cube textures) and several z slices (which were not part
    of pipe_subresource but instead part of pipe_box where appropriate for 3d
    textures) is gone at the resource level.
    Textures, be it array, cube, or 3d, now use a "unified" set of parameters,
    there is no distinction between array members, cube faces, or 3d zslices.
    This is unlike d3d10, whose subresource index includes layer information for
    array textures, but which considers all z slices of a 3d texture to be part
    of the same subresource.
    In contrast to d3d10, OpenGL though reuses old 2d and 3d function entry points
    for 1d and 2d array textures, respectively, which also implies that for instance
    it is possible to specify all layers of a 2d array texture at once (note that
    this is not possible for cube maps, which use the 2d entry points, although
    it is possible for cube map arrays, which aren't supported yet in gallium).
    This should possibly make drivers a bit simpler, and also get rid of mutually
    exclusive parameters in some functions (as z and face were exclusive), one
    potential downside would be that 3d array textures could not easily be supported
    without reverting this, but those are nowhere to be seen.

    Also along with adjusting to new parameters, rename get_tex_surface /
    tex_surface_destroy to create_surface / surface_destroy and move them from
    screen to context, which reflects much better what those do (they are analogous
    to create_sampler_view / sampler_view_destroy).

    PIPE_CAP_ARRAY_TEXTURES is used to indicate if a driver supports all of this
    functionality (that is, both sampling from array texture as well as use a range
    of layers as a render target, with selecting the layer from the geometry shader).

i965: add support for polygon mode on Sandybridge.

This fixes some mesa demos such as fslight/engine in wireframe mode.

i915g: Make sure that new vbo gets updated

Malloc likes to reuse old address as soon as possible this would cause the
new vbo buffer to get the same address as the old. So make sure we set it to
NULL when we allocate a new one. This fixes ipers which will fill up a couple
of VBO buffers per frame.

i915g: don't pot-align stride for tiled buffers

i915g: postpone mipmap/face offset calculation

libdrm-intel can refuse to tile buffers for various reasons. For
potentially tiled buffers the stride is therefore only known after
the iws->buffer_create_tiled call. Unconditionally rounding up to whatever
tiling requires wastes space, so rework the code to not use tex->stride
in the layout code.

Luckily only the mimap/face offset calculation uses it which can easily
be solved by storing an (x, y) coordinate pair. Furthermore this will
be usefull later for properly supporting rendering into the different
levels of tiled mipmap textures.

v2: switch to nblocks(x|y): More in line with gallium and better
suited for rendering into mipmap textures.

st/vega: Bump version to 1.1.

st/vega: Add color transformation support.

Per OpenVG 1.1. A new shader stage is added. It uses the first two
constants of the fragment shader for color transformation parameters.

st/vega: More flexible shader selection.

Divide bits of VegaShaderType into 6 groups: paint, image, mask, fill,
premultiply, and bw. Each group represents a stage. At most one shader
from each group will be selected when constructing the final fragment
shader.

st/vega: Revive mask layer support.

st/vega: Add primitive text support.

Optional features such as auth-hinting are not implemented. There is no
