2007-06-29simplify INIT_SPAN codeBrian
2007-06-29Undo some prev glDraw/CopyPixel changes which fixed a bug in which colors ↵Brian
were overwritten by interpolating attributes. Now just set the span->arrayAttribs mask in glDraw/CopyPixels and be sure we don't overwrite the values in interpolate_active_attribs().
2007-06-21Another round of fixing attribute interpolation for glDraw/CopyPixels.Brian
Need to turn off FRAG_BIT_COL0 in swrast->_ActiveAttribMask when doing glRead/CopyPixels to prevent the user's colors from getting overwritten when a fragment program is active. This was happening in the DRI drivers when MaintainTexEnv program was used (the texenv fragment program was enabled when _swrast_DrawPixels was called). This still isn't an ideal solution, but fixes things for now.
2007-05-20Overhaul/simplify SWvertex and SWspan attribute handling.Brian
Instead of separate fog/specular/texcoord/varying code, just treat all of them as generic attributes. Simplifies the point/line/triangle functions.
2007-04-21Fix color sum bug 10688.Brian
2007-04-11as with prev commit, also fix color index mode zoomed depth copies (bug 10608)Brian
2007-04-11fix zoomed depth copies (bug 10608)Brian
2007-04-05fix color storage bug in convolution pathBrian
2007-04-04Overlapping copies with zoomZ=-1 were broken. See bug 10521.Brian
Need to check for overlapping src/dest regions before computing bottom-to-top vs. top-to-bottom order.
2007-03-26Add _swrast_span_default_secondary_color() for use with glBitmap, ↵Brian
glDrawPixels, etc. Secondary color wasn't getting added to post-texture color when drawing bitmaps, images. See bug 10409.

2007-02-01New SWspanarrays attribs[] array.Brian
Replace texcoord[], varying[], etc. arrays with single attribs[] array, indexed by FRAG_ATTRIB_* values. Eliminates need to copy data into fragment program machine input registers. Will lead to future clean-ups.

2006-10-12Lots of changes to support runtime renderbuffer depths.Brian Paul
_swrast_read_rgba_span() now takes a datatype parameter. New optimization for glReadPixels(format=GL_RGB). New glCopyPixels optimization for the simple, common cases.

2005-11-16Use new gl_framebuffer _Depth/_StencilBuffer fields instead ofBrian Paul
Attachment[BUFFER_DEPTH/STENCIL].Renderbuffer. The former may be wrappers around combined depth/stencil renderbuffers attached at the later points.

IMAGE_CLAMP_BIT if needed. Added ClampVertexColors and ClampFragmentColors to GLcontext in anticipation of upcoming extensions (not fully used yet).

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.
2002-08-07struct sw_span is again allocated on the stack, but the arrays of spanBrian Paul
data are broken out into a new struct span_arrays which is allocated per-context (to avoid huge stack allocations - a problem on Windows). This lets us use span.redStep instead of span->redStep (for example) to hopefully get slightly better performance in the triangle functions.
