If the visual doesn't have an accumulation buffer, the renderbuffer
passed into _swrast_clear_accum_buffer will be NULL anyway. There is
no reason the check the visual. Moreover, the test erroneously checks
the context's visual instead of the visual of the current DrawBuffer.
With FBOs these may be different.

Should fix fdo bug 25837.
|
|
This is part of the GL_EXT_draw_buffers2 extension and part of GL 3.0.
The ctx->Color.ColorMask field is now a 2-D array. Until drivers are
modified to support per-buffer color masking, they can just look at
the 0th color mask.
The new _mesa_ColorMaskIndexed() function will be called by
glColorMaskIndexedEXT() or glColorMaski().

This is another step toward removing a whole bunch of -I flags from
the cc commands. Still need to address driver code...

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...

Compute the region after we've locked (and possibly updated the buffer's size).
Same thing is needed for ctx->Driver.Clear().
|

_swrast_read_rgba_span() now takes a datatype parameter.
New optimization for glReadPixels(format=GL_RGB).
New glCopyPixels optimization for the simple, common cases.

sw_span object, rather than an explicit parameter.

Main driver impacts:
- new code for creating the Mesa GLframebuffer
- new span/pixel read/write code
Some drivers not yet updated/tested.

Moved type conversion and interpolation macros into macros.h
Updated all the files that used to include mmath.h
|
|
|
|
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.
|

indicates the read AND draw color buffer for all software rasterization.
Lots of related clean-ups. See RELNOTES-4.1 for details.
|
|
Added _mesa_printf()
Updated SetDrawBuffer() function in all drivers (ala 4.0.3)
Import 4.0.3/DRI changes.

memory. These can be overridden by applications which need to manage this
memory specially. Contributed by Gerk Huisma.
Also, new code for 8-bit -> 16-bit/channel texture image storage which
fills in the least-significant bits properly.

instead of passing a GLcontext* to ResizeBuffers(), pass a GLframebuffer*.
The idea is that a window can be resized without it being bound to a rendering
context. This makes for a nice clean-up in the XFree86 server-side GLX code.
Renamed ctx->Driver.ResizeBuffersMESA() to ctx->Driver.ResizeBuffers().
|
|
ditch the pb (pixel buffer) code.
Converted point drawing, bitmaps and aa lines to use new span functions.

Replace "RGBAMode" with "rgbMode", etc.
Other minor clean-ups.

into a new directory. Specifically the handling of changes to lighting
lighting space (light in model vs. light in eye) have been revamped.
Moved several derived values used only by swrast into that directory.
Removed direct calls to swrast_flush() from vbrender.c -- pushed into
ctx->Driver.RenderFinish.
Optimized flat-shading case in swrast_setup.

Proper documentation to come.
