* mesa: Remove EXT_blend_subtract extension enable flagIan Romanick2011-09-291-3/+2
| | | | | | | | | | | | | All drivers remaining in Mesa support this extension. This extension is either required or optional features in desktop OpenGL, OpenGL ES 1.x, and OpenGL ES 2.x. This extension was previously not supported on i810, mach64, mga, savage, sis, and tdfx (Voodoo Banshee and Voodoo3).

* mesa: Use ColorLogicOpEnabled instead of _LogicOpEnabledIan Romanick2011-09-191-1/+0
| | | | | | | | | | Since GL_EXT_blend_logic_op is removed, _LogicOpEnabled and ColorLogicOpEnabled always have the same value.

* mesa: Remove support for GL_EXT_blend_logic_opIan Romanick2011-09-191-12/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | Support is removed for four reasons: 1. The implementation was broken with respect to separate blend equations. The GL_EXT_blend_equation_separate spec says: "If EXT_blend_logic_op and EXT_blend_equation_separate are both supported, the logic op blend equation should be supported separately for RGB and alpha as with the other blend equation modes." But Mesa's implementation of GL_LOGIC_OP specifically forbids this. 2. No hardware supported by Mesa can support separate blend equations involving GL_LOGIC_OP. 3. No applications could be found that use this extension. 4. No other Linux OpenGL drivers support this extension.

* | mesa: implement per-buffer color maskingBrian Paul2009-12-291-8/+51
| | | | | | | | | | | | | | | | | | | | | | This is part of the GL_EXT_draw_buffers2 extension and part of GL 3.0. The ctx->Color.ColorMask field is now a 2-D array. Until drivers are modified to support per-buffer color masking, they can just look at the 0th color mask. The new _mesa_ColorMaskIndexed() function will be called by glColorMaskIndexedEXT() or glColorMaski().
* | mesa: per-buffer blend enabled flagsBrian Paul2009-12-291-1/+1
|/ | | | | | | | | | | | | | | ctx->Color.BlendEnabled is now a GLbitfield instead of a GLboolean to indicate blend on/off status for each color/draw buffer. This is infrastructure for GL_EXT_draw_buffers2 and OpenGL 3.x New functions include _mesa_EnableIndexed(), _mesa_DisableIndexed(), and _mesa_IsEnabledIndexed(). The enable function corresponds to glEnableIndexedEXT() for GL_EXT_draw_buffers2 or glEnablei() for GL3. Note that there's quite a few tests for ctx->Color.BlendEnabled != 0 in drivers, etc. Those tests can remain as-is since the mask will be 0 or ~0 unless GL_EXT_draw_buffers2 is enabled.
