- virgl maps VIRGL_FORMAT_B8G8R8X8_UNORM to GL_RGBA8
- _mesa_choose_tex_format() maps GL_RGBA8 to
MESA_FORMAT_R8G8B8A8_UNORM or MESA_FORMAT_A8B8G8R8_UNORM or
MESA_FORMAT_B8G8R8A8_UNORM.
- it ends up in (gl_texture_image *)img->TexFormat
- then in intel (_DRIImage *) image->format.
- on create image, image->dri_format = driGLFormatToImageFormat() (to
ex: MESA_FORMAT_R8G8B8A8_UNORM -> __DRI_IMAGE_FORMAT_ABGR8888)
- on query, intel_lookup_fourcc() -> __DRI_IMAGE_FOURCC_ABGR8888 == GBM_FORMAT_ABGR8888.
For some reason, driGLFormatToImageFormat() doesn't map
MESA_FORMAT_A8B8G8R8_UNORM, so I only check the two possible values I
could find.

the protocol failed to handle larger shaders, this allow
the renderer to reassemble large shaders and recombined
the chunks before passing them to the GLSL translation.
This also enhances the renderer protocol to allow
for some more info in the shader object, and removes
the separate vs/gs/fs variants in favour of a type field
in the shader.
This code ended up in the other file and really wasn't necessary
there.
Remove the transfer code from virglrenderer.c, move into main
renderer file, and match it with the corresponding transfer
reader.
This should at least fix the crash in compressed textures
with ARB_get_texture_sub_image
This might have some fallout but my HSW doesn't expose this due
to some kernel restrictions, so we should handle the situation
and not call TF2 functions
This fixes a number of issues with how transform feedback works
it does requires ARB_transform_feedback3 to work at all, but
hopefully this extension is widespread enough, if not we can
revisit later.
It uses transform feedback objects to store the stream out
state.
Impedance match the gallium and GL transform APIs,
we can't begin before draw vbo but we should only
end when the guest disconnects all buffers
using tfb pause/resume to make things better.
