* Previously, if a fragment program referenced fragment.fogcoord but theBrian Paul2006-10-251-2/+3

* change some bogus comments regarding the base e exponential function used ↵Roland Scheidegger2006-10-252-7/+6

* fix (per-vertex) fog when using ARB_vp by incorporating fog factor ↵Roland Scheidegger2006-10-246-67/+153
| | | | computation into the vertex program (not yet fixed for swtnl). Simplify (and correct) the VTX_TCL_OUTPUT_VTXFMT handling when using vertex programs, turns out it's solely driven by the needs of the past-vertex stage of the pipeline, this should fix lockups with ill-specified applications using vertex programs (for instance applications enabling fog but not writing to fog coord output will now get (conformant) undefined results instead of lockups).

* Emit cliprects in the userspace driver as required, rather thanKeith Whitwell2006-10-2310-66/+81
| | | | | | | | passing them to the kernel. This works because all drawing commands in the 965 driver are emitted with the lock held and the batchbuffer is always flushed prior to releasing the lock. This allows multiple cliprects to be dealt with, without replaying entire batchbuffers and redundantly re-emitting state.

* Changed install filenames to libGL* and libOSMesa* so things work on DarwinBrian Paul2006-10-181-5/+5
| | | | | | | where GL_LIB_NAME = libGL.dylib but the other library name is libGL.1.dylib Unlike other platforms, the version number is in the middle of the name, not at the end. See bug 8671
* Enable GLX_SGI_make_current_read for radeon.Ian Romanick2006-10-185-34/+57
| | | | | | | | | | | | | | Added code to track the drawable bound to the context for reading. In addition, when a drawable is initially bound (for reading or drawing) or when the size of the drawable changes, update the size of the framebuffer object that back the drawable (for software fallbacks). Deprecate the old GetBufferSize interface. Bump the driver date. These changes were tested with wincopy on both direct rendering and accelerated indirect rendering (AIGLX).
* Don't use x/y/w/h params given to Clear().Brian Paul2006-10-182-160/+59
|
* Want to stop passing x/y/width/height to Clear() function.Brian Paul2006-10-1815-122/+168
| | | | | | | The coordinates need to be computed after we've got the hw lock. Code updated to: 1. Ignore all/x/y/width/height/ params passed to Clear func. 2. Pass 0,0,0,0,0 to _swrast_Clear() until they're totally removed.
* Don't pass x/y/width/height to ctx->Driver.Accum().Brian Paul2006-10-184-15/+14
| | | | | Compute the region after we've locked (and possibly updated the buffer's size). Same thing is needed for ctx->Driver.Clear().
* glDrawPixels, line clipping bug fixesBrian Paul2006-10-181-0/+2
|
* Fix broken line clipping.Brian Paul2006-10-181-3/+8
| | | | | | | When both ends of the line were clipped, we were using the new v0 instead of the original v0 when computing the location of the second vertex. Thus, the second vertex's position was incorrect. Thanks to Heath Feather for finding a test case.
* Fix a dangerous use of ASSERT in an else-clause not enclosed in braces.Brian Paul2006-10-181-2/+4
| | | | We've been lucky if this hasn't been causing line rendering bugs.
