CopyTexSubImage when the image type is 1D_ARRAY, because of a
coordinate system mismatch (the Y coordinate in the source image is

i965/gen6+: Fix multisample assertions in CopyTexSubImage hw blitter path.

Commit 045612c (intel: Add an assert for glCopyTexSubImage() being
called on MSAA buffers) added an assertion to intel_copy_texsubimage()
to make sure that multisampling was not in use, based on the
assumption that glCopyTexSubImage() can't legally be used with
multisampling.

However, there is one case where glCopyTexSubImage() can legally be
used with multisampling: when the source buffer is a multisampled
window system buffer.  If the source and destination color formats
don't match, the blorp path will fail, so intel_copy_texsubimage()
will be called.  In this case, we need intel_copy_texsubimage() to
return false so that we fall back to meta to do the copy.  (The
multisampled source buffer won't cause a problem for the meta path,
because it uses glReadPixels, which forces a multisample resolve).

It's still safe to assert that the destination image is
single-sampled, because it's not legal to call glCopyTexSubImage() on
multisampled textures.

Fixes some failures with piglit tests "copyteximage

2d textures benefit a lot from this, a mipmapped 64x64 rgba8 texture

4x4 is chosen because this is the size the jit functions run on, so
making it smaller is going to be a bit more complicated.
It is actually not strictly 4x4 pixel, since we'd want to avoid situations
where different threads are rendering to the same cacheline so we keep

the rasterizer may produce fragments outside the 4x4 blocks present in a

This does not yet fix rendering to buffers (which cannot have any y

intel: Add multisample scaled blitting in blorp engine

In traditional multisampled framebuffer rendering, color samples must be
explicitly resolved via BlitFramebuffer before doing the scaled blitting
of the framebuffer. So, scaled blitting of a multisample framebuffer
takes two separate calls to BlitFramebuffer.

This patch implements the functionality of doing multisampled scaled
resolve using just one BlitFramebuffer call. Important changes involved
in this patch are listed below:
    - Use float registers to scale and offset texture coordinates.
    - Change offset computation to consider float coordinates.
    - Round the scaled coordinates down to nearest integer.
    - Modify src texture coordinates clipping to account for scaling..
    - Linear filter is not yet implemented in blorp. So, don't use
      blorp engine to do single sampled scaled blitting.

V3: Fix nearest filtering issue in scaled blits. Makes failing piglit
fbo-blit-stetch test and framebuffer_blit_functionality_magnifying_blit.test
in gles3 CTS pass.

Observed no piglit, gles3 CTS regressions on sandybridge & ivybridge with
this patch.
