svga: try to avoid index generation for some primitive types
The svga device doesn't directly support quads, quad strips or polygons
so we have to convert those types to indexed triangle lists. But we
can sometimes avoid that if we're drawing flat/constant-colored prims
and we don't have to worry about provoking vertex.

svga: avoid provoking vertex conversion when possible
Provoking vertex comes into play when doing flat shading. But if we know
that all fragments in a primitive are the same color, the provoking vertex
doesn't matter. Check for that case and use whichever provoking vertex
convention is supported by the device.
This avoids generating an index buffer to do the PV conversion.

svga: detect constant color writes in fragment shaders
Examine the fragment shader to try to detect TGSI shaders which use
"MOV OUT[0], CONST[i]" to write a constant value for the fragment color.
In this case, all fragments will have the same color (unless blending is
enabled).
This is a common case for OpenGL code such as: glColor(), glBegin(),
glVertex(), ..., glEnd() when lighting/fog/etc are disabled. In this
case, the Mesa/gallium state tracker actually generates a simple
"MOV OUT[0], CONST[i]" fragment shader.
This will be used by the next commit to avoid provoking vertex conversion
(creating/rewriting an index buffer) when drawing flat-shaded primitives.

The st_RasterPos() function goes to great pains to implement the
rasterpos transformation. It basically uses gallium's draw module to
execute the vertex shader to draw a point, then capture that point's
attributes.
But glRasterPos isn't typically used with a vertex shader so we can
usually use the old/fixed-function implementation which is a lot simpler
and faster.
This can add up for legacy apps that make a lot of calls to glRasterPos.

vbo: fix GL_LINE_LOOP stray line bug
When long GL_LINE_LOOP primitives don't fit in one vertex buffer they
have to be split across buffers. The code to do this was basically correct
but drivers had to pay special attention to the _mesa_prim::begin,end flags
in order to draw the sections of the line loop properly. Apparently, the
only drivers to do this were those using the old 'tnl' module for software
vertex processing.
Now we convert the split pieces of GL_LINE_LOOP prims into GL_LINE_STRIP
primitives so that drivers don't have to worry about the special begin/end
flags. The only time a driver will get a GL_LINE_LOOP prim is when the
whole thing fits in one vertex buffer.
Mostly fixes bug 81174, but not completely. There's another bug somewhere
in the src/gallium/auxiliary/draw/ code. If the piglit lineloop test is
run with -count 4096, rendering is correct, but with -count 4097 there are
stray lines. 4096 is a magic number in the draw code (search for "4096").
Also note that this does not fix long line loops in display lists. The
next patch fixes that.

Brian Paul [Thu, 15 Oct 2015 18:33:00 +0000 (12:33 -0600)]
vbo: reduce number of vertex buffer mappings for vertex attributes
Whenever we got a glColor, glNormal, glTexCoord, etc. call outside a
glBegin/End pair, we'd immediately map a vertex buffer to begin
accumulating vertex data. In some cases, such as with display lists,
this led to excessive vertex buffer mapping. For example, if we have
a display list such as:
glNewList(42, GL_COMPILE);
glBegin(prim);
glVertex2f();
...
glVertex2f();
glEnd();
glEndList();
Then did:
glColor3f();
glCallList(42);
We'd map a vertex buffer as soon as we saw glColor3f but we'd never
actually write anything to it. Note that the vertex position data
was put into a vertex buffer during display list compilation.
With this change, we delay mapping the vertex buffer until we actually
have a vertex to write to it (triggered by a glVertex() call). In the
above case, we no longer map a vertex buffer when setting the color and
calling the list.
For drivers such as VMware's, reducing buffer mappings gives improved
performance.
