2005-10-27Add support for GL_EXT_stencil_wrap, from hearing that the windows drivers didEric Anholt
it, and guessing that the two remaining entries in the 3-bit values were the new funcs. Tested with modified stencilwrap test. Also, remove the commented fallback stuff -- more modification to stencilwrap suggests that those issues were just from span readback, not stencil implementation.
2005-10-27Bug #1028: Add hardware-accelerated stencil support to r128. Testing withEric Anholt
stencilwrap reported many issues with various modes. Some of these were complicated by the fact that spans are broken (Bug #1615), but some appear to be real bugs. However, while spans remain broken, I found that visual results were better by avoiding fallbacks rather than avoiding just a broken stencil implementation. Note that this required changing the depth spans at 24+8bpp into read-modify-write cycles. It would be nicer as a single write with a mask, but the kernel span blits turn off masking.

2004-06-04Enable GL_EXT_blend_subtract and GL_NV_blend_square.Ian Romanick
GL_EXT_blend_subtract was already enabled via GL_ARB_imaging, but now one of the added modes is supported in hardware. GL_NV_blend_square was tested with progs/tests/blendsquare on an Rage128 Pro with PCI ID 1002:5046. I know there are some differences with some versions of the chip.
