This improves performance and avoids int/float/int conversion problems that
can introduce errors during glCopyTexImage(). Another fix for the depth peeling
algorithm.
glide is no longer compiled with stand-alone libGL, so this will not link.
There are still the glide config files. some code in demos and the
GLX_MESA_set_3dfx_mode code which could be removed.
The later takes a type parameter so we can match uniforms or attributes/inputs.
Used by the GL_ACTIVE_ATTRIBUTE_MAX_LENGTH and GL_ACTIVE_UNIFORM_MAX_LENGTH
queries. Fixes problem reported by Brad King in VTK.
This is a bit of a hack for now because the tnl module is using the swrast
module to fetch texels. The texture fetch/filter code should probably be
moved into the main/ module since it doesn't really depend upon other
swrast code.
Otherwise, the clip/interp code was finding VB->EdgeFlag to be non-null and
reading/writing it when the memory may have been freed earlier in free_space().
This fixes several VTK segfaults/failures reported by Brad King @ Kitware.
This way we have a hw context so that we can take the hardware lock.
Also, at this point, AIGLX isn't locked with the X server context as it is
at screen creation.
use VertexProgram._Current instead of VertexProgram.Current in a few more places.
Only fixup fogc and psiz in case this is really a nv program (others are fine
if undefined), and fix this case up so the values actually get written.
OK, _all_ extensions that might get enabled by the driver need to be in the
card_extensions[] list. driInitExtensions() is called at least twice: first
during screen creation, then once for each context that's created.
The first call sets up the dispatch table. The second call just sets the
extension enable/disable flags.
Previously, this limited us to 12 temp regs for vertex programs. Many vertex
shaders could exceed that. This forces us to stop using t_vb_arbprogram.c
for now because of its particular register indexing scheme. Need to increase
bits allocated for register indexing, etc.
