The size of some core Gallium state structures has changed so the
padding on some cell structs needed to be adjusted to keep them
a multiple of 16 bytes.
wgl: Do not reach out and destroy contexts on cleanup.
Simply skip cleanup when contexts are still active.
This addresses two issues:
- in some situations the ICD DLL may be unloaded before the DLL that is
using GL contexts is, so we may receive GL calls after stw_cleanup.
- when aborting (exception, or control-c) the contexts may have been left
in an inconsistent state and attempting to destroy can cause
unpredictable results.
Windows doesn't really expect things to fail at this point -- it
will try many times until it finally gives up, worse, something bad
happens.
The WGL state tracker will gracefully decline to do work even when it
is loaded.
svga: check min_index, max_index before assertions
It's possible for min_index and max_index to be ~0 if the min/max
values were not actually set or computed in the state tracker.
Skip some assertions in that case.
This only effects the debug build error checking.
(cherry picked from commit 408f32dc16)
gallium: make max_anisotropy a unsigned bitfield member
saves us a dword in sampler state, hw can't do non-integer aniso degree anyway.
To allow aniso 1x (which seems of dubious value but some hardware (radeons)
have such a mode, and even d3d allows specifiying it) redefine anisotropic
filtering as disabled only if max_anistropy is 0.
st/mesa: fix gallium texture level selection for RTT
Fixes invalid texture level when rendering to a texture where
GL_BASE_LEVEL > 0.
This will be cherry-picked to the 7.7 branch after additional
testing.
