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...

2007-10-17Don't call the driver clear hook when the effective scissor rectangle is empty.Michel Dänzer
2007-08-18remove dead code left over after fixing GL_READ/DRAW_BUFFER state issuesBrian
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.
2007-08-16update comments, etc related to Read/DrawBuffer stateBrian
2007-07-20fix bogus recently introduced function param commentsRoland Scheidegger
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.

Main driver impacts: - new code for creating the Mesa GLframebuffer - new span/pixel read/write code Some drivers not yet updated/tested.
2005-02-26Rename _mesa_update_buffers() to _mesa_update_draw_buffer_bounds() and doBrian Paul
additional checks. Replace _mesa_init_buffers() with _mesa_init_scissor() and _mesa_init_multisample().

2004-03-21Implemented support for software-based AUX color buffers.Brian Paul
Only available with Xlib driver for now. Assorted clean-ups related to Draw/ReadBuffer(). Renamed FRONT_LEFT_BIT -> DD_FRONT_LEFT_BIT, etc.

2003-04-29don't try to clear non-existant buffersBrian Paul
2003-03-01Killed mmath.[ch]. Moved low-level functions/assembly code into imports.[ch]Brian Paul
Moved type conversion and interpolation macros into macros.h Updated all the files that used to include mmath.h
2002-10-24Header file clean-up:Brian Paul
1. Remove all.h and PC_HEADER junk. 2. Rolled mem.c and mem.h into imports.c and imports.h 3. Include imports.h instead of mem.h Restore _mesa_create/initialize_context() to be like they were in 4.0.4 New wrappers for a few std C functions: _mesa_atoi(), _mesa_strstr(), etc.
2002-10-11Another round of glRead/DrawBuffer() clean-ups and simplifications.Brian Paul
Replaced ctx->Color._DriverDrawBuffer with swrast->CurrentBuffer. Replaced ctx->Pixel._DriverReadBuffer with ctx->Pixel._ReadSrcMask. swrast->Driver.SetBuffer() takes FRONT/BACK_LEFT/RIGHT_BIT values now. Added tokens and code for GL_AUX buffers, for completeness.
