Pass a gl_format to intel_create_renderbuffer() instead of GLenum.
Add cases for MESA_FORMAT_XRGB8888 textures and renderbuffers.
However, we don't yet create any renderbuffers or textures with that
format. It seems the default alpha value is zero instead of one.
Need to investigate that first.

It doesn't work reliably even when all the prerequisite checks are made.

The textured quad path is slightly faster and will work with POT textures
on i945.
|
|
Move all the metaops to a dri_metaops file and port radeon/intel
to use the new common meta ops code.
|
|
RasterPos[2] is already sent through the window transform, which includes
DepthRange handling. So make DepthRange for the metaops a noop.
Fixes a failure in oglconform depthrange.c

Even after fixing bugs in this code, it doesn't make me feel any cleaner.
Fixes piglit stencil-drawpixels.

Make this be its own function for setup/teardown of the binding of these
texcoords. No performance difference in the engine demo (I just felt dirty
not using a VBO for this), and I think it should be more resilient to
interference from current GL state.

Found while debugging cairo-gl.

As for glBitmap, it needs to be an NDC coord in [-1,1].

|
There was a note in state.c about _Active deserving to die, and there were
potential issues with it due to i965 forgetting to set _UseTexEnvProgram.
Removing both simplifies things.

The DrawPixels path was missing glViewport care, so blender's toolbar icons
would go to the wrong places.
Bug #19118.
|
|
GL_COLOR_INDEX mode is just like other normal formats (that is, not
depth/stencil) and is uploaded fine by TexImage.

This is nasty because there's no way in GL to output data to the stencil
buffer directly, so we have to do a dance to wrap the depth/stencil buffer
in an ARGB renderbuffer.
Improves performance of several oglconform testcases by better than a factor
of 2.

Improves performance of some oglconform regression tests 9x.

Most of these were to ensure that caches got synchronized between 2d (or meta)
rendering and later use of the target as a source, such as for texture
miptree setup. Those are replaced with intel_batchbuffer_emit_mi_flush(),
which just drops an MI_FLUSH. Most of the remainder were to ensure that
REFERENCES_CLIPRECTS batchbuffers got flushed before the lock was dropped.
Those are now replaced by automatically flushing those when dropping the lock.

Mesa demos tend to leave blending on but in GL_ONE/GL_ZERO, or
GL_SRC_ALPHA/GL_ONE_MINUS_SRC_ALPHA with a source alpha of 1.0.

The fencing code is not required, and waiting on the fences defeated one of
the purposes of the extension, which is to allow asynchronous readpixels.
|
|
Otherwise, glDrawBuffer(GL_NONE); glDrawPixels() results in a segfault when
we try to emit the color buffer state during setup.
|
|
In order to optimize DrawPixels, the i915 texenv program isn't
applied to swrast DrawPixels in the i915 driver. This causes this
program isn't applied to any following swrast functions. Resetting
the swrast state fixes this issue. Fix #13614
