* Header file clean-up:Brian Paul2002-10-241-2/+2
| | | | | | | | 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.
* struct sw_span is again allocated on the stack, but the arrays of spanBrian Paul2002-08-071-20/+23
| | | | | | | 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.
* Allocate a sw_span struct in the swrast context instead of allocating itBrian Paul2002-04-191-2/+2
| | | | | on the stack frame in the point/line/triangle functions. (Klaus Niederkrueger) This should solve the performance problem Karl found on Windows.
* casts to fix GLint/GLuint mismatchesBrian Paul2002-04-191-11/+12

* Klaus Niederkrueger's latest changes: use INIT_SPAN() to init span primitiveBrian Paul2002-04-121-4/+5
| | | | type, width, interp mask and array mask.
* sw_span can now hold x/y arrays of fragment positions - getting ready toBrian Paul2002-02-021-1/+4
| | | | | ditch the pb (pixel buffer) code. Converted point drawing, bitmaps and aa lines to use new span functions.
* Clean-up and optimize alpha test code.Brian Paul2002-01-311-345/+165
| | | | Major clean-up of pixel zoom code.
* More span improvements. Removed _mesa_write_monocolor_span().Brian Paul2002-01-281-9/+3
| | | | | Removed last of span.filled* flags and Klaus's macros. More simplification of triangle functions.
* More span clean-up, mostly texture-related.Brian Paul2002-01-281-4/+3
| | | | | _mesa_rasterize_span() is gone, replaced by new _mesa_write_textured_span(). Removed some unneeded triangle functions - more simplification possible.
* LOTS of changes, building upon Klaus's work.Brian Paul2002-01-271-66/+90
| | | | | struct sw_span is used throughout span/fragment processing. This is leading to less code and more chances for optimization.

* Apply antialiasing coverage factor to alpha after texture application,Brian Paul2001-05-151-5/+4

* interpolate fog valus as floats, not fixed - fixed the swrast fog problemBrian Paul2001-05-031-7/+7

* lots of gl_*() to _mesa_*() namespace clean-upBrian Paul2001-03-031-19/+19

* Reorganized software rasterizer as a module which manages its own state,Keith Whitwell2000-11-051-1/+2
| | | | | | with tighter interfaces with the rest of the world. Proper documentation to come.
* Moved software rasterizer functionality to new directory.Keith Whitwell2000-10-311-0/+453
