2009-01-23Track two sets of back-face stencil stateIan Romanick
Track separate back-face stencil state for OpenGL 2.0 / GL_ATI_separate_stencil and GL_EXT_stencil_two_side. This allows all three to be enabled in a driver. One set of state is set via the 2.0 or ATI functions and is used when STENCIL_TEST_TWO_SIDE_EXT is disabled. The other is set by StencilFunc and StencilOp when the active stencil face is set to BACK. The GL_EXT_stencil_two_side spec has more details. http://opengl.org/registry/specs/EXT/stencil_two_side.txt
2009-01-22mesa: enable ARB_fbo for s/w driversBrian Paul
2009-01-22mesa: avoid calling _mesa_test_framebuffer_completeness() more than neededBrian Paul
When we change a FBO's attachments, set _Status=0. Before using an FBO, check if status != GL_FRAMEBUFFER_COMPLETE. Also, fix missing GL_FRAMEBUFFER_INCOMPLETE_MULTISAMPLE status.
2009-01-22mesa: fix some renderbuffer/framebuffer delete semanticsBrian Paul
Need to unbind buffers if referenced by the current read/draw pointers when being deleted.
2009-01-22mesa: add support for GL_DEPTH_STENCIL_ATTACHMENT point.Brian Paul
Used to set both the depth and stencil attachment points to one renderbuffer of texture.
2009-01-22mesa: additional FBO error checking for multisample-related thingsBrian Paul
Plus some new comments.
2009-01-22mesa: update Visual.samples field in _mesa_update_framebuffer_visual()Brian Paul
2009-01-22mesa: refactor glRenderbufferStorage(), glRenderbufferStorageMultisample() codeBrian Paul
Use a common helper routine for both functions.

2009-01-22mesa: added GL_MAX_SAMPLES query for GL_ARB_fboBrian Paul

2009-01-22mesa: call fbo_incomplete() if driver marks FBO as incomplete (debug only)Brian Paul
2009-01-22mesa: update update_framebuffer_size() for ARB_fbo and mixed renderbuffer sizesBrian Paul
2009-01-22mesa: added ctx->Driver.ValidateFramebuffer() callbackBrian Paul
Called from the _mesa_test_framebuffer_completeness() function to give the driver the chance to make a framebuffer as incomplete if it doesn't meet some specific hardware restriction.
2009-01-22mesa: add new ARB_fbo queries, fix some error testsBrian Paul
2009-01-22mesa: add new ColorEncoding and ComponentType to gl_renderbufferBrian Paul
2009-01-22mesa: additional FBO/RB id error checking for ARB_fboBrian Paul
It's illegal to bind a FBO/RB id that didn't come from glGenRender/Framebuffer().

2009-01-21mesa: add some debug assertions to detect null current texture object pointersBrian Paul
See bug #17895. These assertions could be removed when this is resolved.

2009-01-16mesa: remove GL_DEPTH_TEST + no depth buffer testBrian Paul
One could enable depth testing before binding an FBO that has a depth buffer so this test is no longer useful or correct.

2009-01-14mesa: fix incorrect transformation of GL_SPOT_DIRECTIONBrian Paul
This was changed between GL 1.0 and 1.1. Mesa still had the 1.0 behaviour.

2009-01-08mesa: set version string to 7.3-rc1Brian Paul
2009-01-07mesa: Remove _Active and _UseTexEnvProgram flags from fragment programs.Eric Anholt
There was a note in state.c about _Active deserving to die, and there were potential issues with it due to i965 forgetting to set _UseTexEnvProgram. Removing both simplifies things. Reviewed-by: Brian Paul <brianp@vmware.com>

2008-12-31mesa: increase max texture image units and GLSL samplers to 16Brian Paul
The max texture coord units is still 8. All the fixed-function paths are still limited to 8 too. But GLSL shaders can use more samplers now. Note that some texcoord-related data structures are declared to be 16 elements in size rather than 8. This just simplifies the code in a few places; the extra elements aren't accessible to the user. These changes haven't been extensively tested yet, but sanity checking has been done. It should be possible to increase the max image units/samplers to 32 without doing anything special. Beyond that we'll need longer bitfields in a few places.

2008-12-19Add do_row_3d for mipmapping 3D texturesIan Romanick
Previously 3D textures were mipmapped using multiple passed through the 2D mipmap generation code. This had 3 disadvantages. First, the extra passes were slow. Second, this required the allocation of a temporary buffer to hold intermediate data. Third, and most important, the extra passes caused loss of additional bits due to integer division / bit-shifting. With this change, our mipmapgen conformance test passes for non-compressed texture formats.

2008-12-18mesa: Clip copytexsubimage to read framebuffer bounds, not scissor region.Eric Anholt
2008-12-18mesa: Correct _mesa_clip_to_region() off-by-one.Eric Anholt
Note how if: x + width == xmax + 0: width -= 0 x + width == xmax + 1: width -= 0 x + width == xmax + 2: width -= 1 So, the function was clipping to [xmin, xmax+1), not [xmin, xmax) like it was supposed to. Same for ymax.
2008-12-17mesa: remove unneeded _mesa_reference_fragprog() callBrian Paul
The subsequent if/else cases always call _mesa_reference_fragprog() anyway.
