2009-11-05mesa: fix infinite loop bug in _mesa_drawbuffers()Brian Paul
Fixes bug 24946. This regression came from 8df699b3bb1aa05b633f05b121d09d812c86a22d.

2009-05-01mesa: in glReadBufer() set _NEW_BUFFERS, not _NEW_PIXELBrian Paul
Since GL_READ_BUFFER is historically part of the gl_pixel_attrib group it made sense to signal changes with _NEW_PIXEL. But now with FBOs it's also part of the framebuffer state. Now _NEW_PIXEL strictly indicates pixels transfer state changes. This change avoids framebuffer state validation when any random bit of pixel-transfer state is set. DRI drivers updated too: don't check _NEW_COLOR when updating framebuffer state. I think that was just copied from the Xlib driver because we care about dither enable/disable state there.
2009-03-12mesa: fix glRead/DrawBuffer(GL_AUXn) error valueBrian Paul
If GL_AUX[123] are passed to glRead/DrawBuffer() when those buffers don't exist, need to generate GL_INVALID_OPERATION, not GL_INVALID_ENUM. This regression came from commit 555f0a88182e2b1af809b2d97abdac02814a2f28
2009-03-02mesa: remove unused AUX buffersBrian Paul
Remove all references to aux buffers 1..3. Keep AUX0 around for now just in case, but it'll probably go too someday. I don't know of any OpenGL drivers since the IRIX days that support aux color buffers.
2009-02-12glDrawBuffers(n==0) is validRobert Ellison
According to the GL spec, calling glDrawBuffers() with n == 0 is a valid operation (and essentially prevents drawing to any buffers). But _msa_DrawBuffersARB() was producing a GL_INVALID_VALUE error in this case. This fix adjusts the error check, and makes a small change to the ctx->Driver.DrawBuffer() call below to ensure that, if n == 0, Driver.DrawBuffer() is called with GL_NONE and that buffers[0] is *not* referenced in this case (since we don't know whether it is valid). Internal identifier: 365833

A first attempt at moving gallium onto a branch directly off master... It will be interesting to see how much work this takes to get running.

2008-07-02mesa: fix issues around multisample enableRoland Scheidegger
multisample enable is enabled by default, however gl mandates multisample rendering rules only apply if there's also a multisampled buffer.

2008-01-09fix bug 13978: glDrawBuffersARB() didn't set all necessary stateBrian
2008-01-06Replace gl_framebuffer's _ColorDrawBufferMask with _ColorDrawBufferIndexesBrian
Each array element is now a BUFFER_x token rather than a BUFFER_BIT_x bitmask. The number of active color buffers is specified by _NumColorDrawBuffers. This builds on the previous DrawBuffer changes and will help with drivers implementing GL_ARB_draw_buffers.
2008-01-06Simplify ctx->_NumColorDrawBuffers, _ColorDrawBuffers and fix bug 13835.Brian
These fields are no longer indexed by shader output. Now, we just have a simple array of renderbuffer pointers. If the shader writes to gl_FragData[i], send those colors to the N _ColorDrawBuffers. Otherwise, replicate the single gl_FragColor (or the fixed-function color) to the N _ColorDrawBuffers. A few more changes and simplifications can follow from this...

2008-01-01additional GL_COLOR_ATTACHMENTx_EXT cases (bug 13767)Brian
2007-10-30Set _NEW_BUFFERS in glRead/DrawBuffer().Brian
Previously, we set _NEW_PIXEL and _NEW_COLOR in these functions, respectively. That correponds to the GL attribute groups, but doesn't make much sense otherwise. This could improve validation efficiency in a few places too. It looks like all the drivers are already checking for _NEW_BUFFERS in the right places (since that's the bit for FBO state) so we can trim out _NEW_PIXEL and _NEW_COLOR at any time.
2007-10-17Add some FLUSH_CURRENT() calls.Brian
Without these we can find ourselves in _mesa_load_state_parameters() computing derived lighting/material values whhen the current material properties haven't been updated from the VBO. This may be a somewhat wide-spread problem that needs more attention...

2007-08-16Rework the GL_READ_BUFFER, GL_DRAW_BUFFER state repairs that Roland ↵Brian
previously did. Basically, in update_framebuffer() (which should be called after an FBO is bound with MakeCurrent or BindFramebuffer) we check if the FBO is a window-system FBO. If it is, update the FBO's GL_READ/DRAW_BUFFER state according to the context state. Old code still in place but disabled with #if 0 / #endif.

2007-07-19fix mesa's handling of fbo's / window fb (again)Roland Scheidegger
Make sure the relevant fields in window fbs get updated at appropriate time (those are NOT the same as fbos!!!), and fix up related code accordingly. This is a bit ugly, but there's a reason the issues section in EXT_fbo is a couple hundred pages long... Hopefully correct now.
