2010-04-19gallium/draw: use correct rasterization state for wide/AA points/linesBrian Paul
When points or lines are decomposed into triangles, we need to be sure to disable polygon culling, stippling, "un-filled" modes, etc. This patch sets the rasterization state to disable those things prior to drawing points/lines with triangles, then restores the previous state afterward. The new piglit point-no-line-cull test checks this problem & solution.
2010-04-08st/mesa: fix glDrawPixels(GL_DEPTH_COMPONENT) regressionBrian Paul
Commit 1454f20a991ddda35f1a2ffda953012078b407ba caused the regression. When the vertex shader emitted both a texcoord and color we were grabbing the wrong vertex attributes. Fix the draw_quad() code to put texcoords in slot[1] and color in slot[2]. That's a bit cleaner than changing the vertex shader code. Tested with progs/tests/zreaddraw.c

2010-03-18st/mesa: s/unpack/pack/ to be more consistentBrian Paul
2010-03-17st/mesa: fix glCopyPixels bugs/crashes when src region need clippingBrian Paul
Use the _mesa_clip_readpixels() function to clip the src region against the buffer's bounds. Neatly, the resulting pixel unpack object's SkipPixels/SkipRows fields can be used to determine the position of the region in the destination texture. Fixes crash in progs/samples/copy.c and probably other cases.

2010-03-11st/mesa: fix st_set_framebuffer_surface() state validationBrian Paul
Set the _NEW_BUFFERS flag and remove the code which updated the parent framebuffer size. Normal Mesa state validation will do that. Fixes issues with Warsow on r300g and possibly other bugs.
2010-03-10st/mesa: fix incorrect glCopyPixels between window/FBOBrian Paul
There was a DrawBuffer/ReadBuffer typo and we were neglecting to invert the texture coords when copying from a window to an FBO. Plus, add some surface dump/debug code (disabled). (cherry picked from commit 34f02071618624263eba839b5aeb930d0e794078)
2010-03-10st/mesa: fix incorrect glDrawPixels into FBOBrian Paul
We weren't inverting the textured quad when drawing into an fbo. (cherry picked from commit 8d3f629a13afb0d6acafc7a007972fdc5efe6847)
2010-03-08st/mesa: don't detach renderbuffer, surface in st_finish_render_texture()Brian Paul
There's no reason to release the renderbuffer from the framebuffer object or release the gallium surface in this function (they're reference counted). In fact, we don't want to do this because we may later use the texture as a pixel source (ex: glBlitFramebuffer) and need the surface. Fixes fd.o bug 26923 and is part of the fix for bug 26932.

2010-02-18Revert "st/mesa: Make the frontbuffer visible on st_flush(PIPE_FLUSH_FRAME)."Francisco Jerez
We probably don't want to propagate this condition to the pipe driver, this reverts commit f455ca6490fcb65781b21f81c7117bd923e250d1 and the dri_update_buffer flush altogether until an agreement is reached.
2010-02-18st/mesa: always call FLUSH_CURRENT before st->pipe->flush()Keith Whitwell
Undoes part of commit f455ca6 which would permit pipe->flush() to be called while the VBO module still had its buffers mapped. Some drivers care deeply about this. Sorry for not spotting this earlier.
2010-02-17st/mesa: Make the frontbuffer visible on st_flush(PIPE_FLUSH_FRAME).Francisco Jerez
So far the frontbuffer was only being flushed on st_glFlush and st_glFinish, however, a co-state tracker may need to make sure that any frontbuffer changes are already on its way to the actual front. The dri2 state tracker will need this for event-driven GL applications to resize properly (It could also be done calling "dri_flush_frontbuffer", but that way we would flush unnecessarily in the double-buffered case). Additionally this patch avoids flushing the mesa rendering cache if PIPE_FLUSH_RENDER_CACHE wasn't specified.

2010-02-12st/mesa: restore draw rasterization stage after rasterposBrian Paul
This fixes invalid calls to rastpos_point/line/tri() that can occur when glRasterPos() is called while in feedback or selection mode. (cherry picked from commit b3c7dc6ff232eb4c5ff6b0ddcfa90bcb56f78df1)
2010-02-12st/mesa: improved draw_range_elements codeBrian Paul
Don't use pipe->draw_range_elements() if min_index=max_index=~0 since that doesn't provide any useful info. Also, implement the loop around pipe->draw_range_elements() when nr_prims > 1.
