* Add a facility to route all rasterization through a fragment programKeith Whitwell2005-05-041-2/+2
| | | | | | | | | | | which is automatically generated to match the current texture environment state. Introduces a new value ctx->FragmentProgram._Active which is true when either _Enabled is true or there is such a fragment program ready to run. To test out on a driver running the software rasterizer, set MESA_TEX_PROG=t in the environment. It goes without saying that performance is lower for the software rasterizer in this mode.

* struct sw_span is again allocated on the stack, but the arrays of spanBrian Paul2002-08-071-40/+39
| | | | | | | 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.

* Remove 'pv' parameter from Line/Tri/Point funcs. The provoking vertexKeith Whitwell2001-01-051-9/+9
| | | | | | | | | | | | | | is always the last vertex parameter. Modify clipping to preserve pv colors. Modify swrast and X11 driver to expect the pv in the last vertex (was looking in the first vertex previously). Remove all handling of flatshading from swrast_setup. Allow drivers to override the unclipped render tabs in tnl_render_stage directly. (Like in 3.4). Removed fxsimplerender stage. Modified t_vb_rendertmp.h to remove the need for 'parity' arguments in RENDER_TRI macros.

GL conformance tests for AA lines (but not tried yet). TODO: improve code sharing with the AA triangle code.
