* fix bug 13978: glDrawBuffersARB() didn't set all necessary stateBrian2008-01-091-0/+2
|
* Replace gl_framebuffer's _ColorDrawBufferMask with _ColorDrawBufferIndexesBrian2008-01-061-45/+44
| | | | | | | 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.
* Simplify ctx->_NumColorDrawBuffers, _ColorDrawBuffers and fix bug 13835.Brian2008-01-061-2/+3
| | | | | | | | | | | 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...

* remove dead code left over after fixing GL_READ/DRAW_BUFFER state issuesBrian2007-08-181-47/+0

* Rework the GL_READ_BUFFER, GL_DRAW_BUFFER state repairs that Roland ↵Brian2007-08-161-5/+81
| | | | | | | | | 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.
* update comments, etc related to Read/DrawBuffer stateBrian2007-08-161-2/+5

* fix mesa's handling of fbo's / window fb (again)Roland Scheidegger2007-07-191-23/+49
| | | | | | | | 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.
