This is to unify the xmesa code across xserver DDX'es. The call is intented for
XGL, but it does not hurt to call for other DDX'es. In fact it was not guarded
against XGL when it was first added in xserver.
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.
