If the currently bound FBO isn't yet validated it's possible for
rgbMode to be zero so we'll lose the texture enable.
This could fix some FBO rendering glitches, but I don't know of
any specific instances.

I believe this is the last of the shader-related functions that needed
display list treatment.

Note: there are more glUniform functions to compile...

I'm not 100% sure there'll be a 7.5.2 release, but just in case.

We need to clamp/saturate after each texenv stage, not just the last one.
Fixes glean texEnv failure for softpipe (and probably other fragment program-
based drivers).

Fixes piglit fp-fog failure with gallium.

Conditionalize MAX_WIDTH / MAX_HEIGHT defines so that users can
set them via CFLAGS.

Put the assertions after the error checks.

We were passing the address of a float to functions that would deref the
pointer as an array.

Allocate dlist images after error checking.
Record GL_OUT_OF_MEMORY when we can't make a copy of an image.

If glBlitFramebuffer() is called with GL_DEPTH_BUFFER_BIT or
GL_STENCIL_BUFFER_BIT and the src/dst depth/stencil buffers are absent,
report an error.

Funny thing is I annotated this dependency in
e5f63c403b767f9974e8eb5d412c012b8a69287f, but didn't actually use it.

I started looking into why _NEW_ARRAY punishes us, and while annotating
dependencies noticed that a bunch of dependencies were missing.

Move a chunk of code out of _mesa_error()
|
|
Remove early and unused snprintf and where[] string.
|

Buggy apps can generate thousands of mesa_error calls. Don't need
to keep calling getenv to retreive the same MESA_DEBUG string each
time.

The texture object's border color used to be stored as GLchan but it's
been GLfloat for a while now.

The values 2147483648.0 and 4294967294.0 are too larget to be stored in single
precision floats. Forcing these to be singles causes bits to be lost, which
results in errors in some pixel transfer tests.
This fixes bug #22344.

The semantics are a little different for shaders vs. fixed-function when
trying to use an incomplete texture. The fallback texture returning
(0,0,0,1) should only be used with shaders. For fixed function, the texture
unit is truly disabled/ignored.
Fixes glean fbo test regression.

Only short-circuit material call if *all* statechanges from this call
are cached. Some material calls (eg with FRONT_AND_BACK) change more
than one piece of state -- need to check all of them before returning.
Also, Material calls are legal inside begin/end pairs, so don't need
to be as careful about begin/end state as with regular statechanges
(like ShadeModel) when caching. Take advantage of this and do better
caching.
|
|
Statechanges which occur before the first End in a display list may
not be replayed when the list is called, in particular if it is called
from within a begin/end pair.
Recognize vulnerable statechanges and do not use them to fill in the
state cache.
|
|
When compiling a display list containing a CallList, it is necessary to
invalidate any assumption about the GL state after the recursive call
completes.
|
|
Need this to pick up fixes for per-vertex materials.

|
|
Varying material inputs were not being picked up from the same slots
where the VBO code is currently placing them (GENERIC0 and above).
Most often they were just being ignored.
|
|
Reorganization of ShadeModel to avoid flushing vertices too often
ended up never flushing vertices due to omitted line of code.
|
|
Add a simple version of _mesa_lookup_enum_by_nr() which expects a primitive
enum (GL_POINTS..GL_POLYGON). This avoids some annoying duplicates
when looking up primitives, such as the GL_FALSE/GL_POINTS clash.
|
|
Currently, state-changes in mesa display lists are more or less
a verbatim recording of the GL calls made during compilation.
This change introduces a minor optimization to recognize and eliminate
cases where the application emits redundant state changes, eg:
glShadeModel( GL_FLAT );
glBegin( prim )
...
glEnd()
glShadeModel( GL_FLAT );
glBegin( prim )
...
glEnd()
The big win is when we can eliminate all the statechanges between two
primitive blocks and combine them into a single VBO node.
This commit implements state-change elimination for Material and ShadeModel
only. This is enough to make a start on debugging, etc.

16 is the limit for now because of various 32-bit bitfields.

This is the start of a glsl-continue-return feature branch to support
a GLSL code generator option for 'continue' and 'return' statements.
Some targets don't support CONT or RET statements so we'll need to
try to generate code that does not use them...
