intel: Use depth buffer from ctx.DrawBuffer in copypix_src_region()
This function was using intel->depth_region, which is the static region
for the DRI1 depth buffer. This code has always been broken with DRI2
but I suspect it doesn't get excersized much.
Push __driDriverExtensions out of dri_util.c and into the drivers
This lets the individual drivers select which extensions to advertise.
Specifically, most drivers (tdfx, sis, savage etc) don't support DRI2
but the shared extension list in dri_util.c does list the DRI2 extension.
Pushing the list into the drivers, lets us avoid listing the DRI2
extension for drivers that don't support it.
As part of the DRI driver interface rewrite I merged __DRIscreenPrivate
and __DRIscreen, and likewise for __DRIdrawablePrivate and
__DRIcontextPrivate. I left typedefs in place though, to avoid renaming
all the *Private use internal to the driver. That was probably a
mistake, and it turns out a one-line find+sed combo can do the mass
rename. Better late than never.
This adds missing pkg-config lookup for intel and moves the radeon
lookup into a case...esac so it's only looked up when one or more of
the radeon drivers are enabled.
Only enable verbose NoOp dispatch if DEBUG is defined
By default we generate a function per GL entry point to warn if it's
called without a context set. This is to allow the function to print
it's name in the warning. By using a generic function that doesn't print
the function name in the non-DEBUG case, we reduce libGL size from
320008 bytes to 283144 bytes (11%).
The GLUTAPI #define used in the header file to mark the font structs
visible wasn't kicking in because of the #define glutBitmap9By15 XXX
prior to #include <GL/glut.h>. High quality code... worked around by
copying the GLUTAPI specifier to the invidual C files.
