vertex_program struct.
Allow switching between regular and vertex_program implementations
of fixed function TNL with the MESA_TNL_PROG environment var
(previously this required recompilation).
Ensure program compilation only references program data, not the
wider context. This means that compiled programs only need to be
invalidated when the program string changes, not on other state
changes.
- remove input/output fields, input tracking removed.
- remove state fields, the validate function now called
on every statechange.
- add an explicit 'create' function.
Add in code to build vertex program to implement current t&l state. Still
disabled, but turn on with a #define in t_vp_build.h.
clear that these are owned by t_vb_render.c.
Make swrast_setup opaque - it now hooks itself directly into
tnl->Driver.Render.*. Add a _swsetup_Wakeup() call that does this.
Update X11 (tested), osmesa and FX drivers for this change.
FX compiles but is probably broken as the changes there are large. It was the
only remaining driver that used the internal _swsetup_ functions for
interp and copy_pv. This usage has been replaced with code from the DRI
tdfx driver.
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.
New array_cache module
Support 8 texture units in core mesa (now support 8 everywhere)
Rework core mesa statechange operations to avoid flushing on many
noop statechanges.
math: Provides basic matrix and vector functionality that
might be useful to multiple software t&l
implementations, and is used by core mesa to
manage the Model, Project, etc matrices.
tnl: The real transform & lighting code from core mesa,
including everything from glVertex3f through vertex
buffer handling, transformation, clipping, lighting
and handoff to a driver for rasterization.
The interfaces of these can be further tightened up, but the basic
splitting up of state and code move is done.
