not respecting the coords (or perhaps interpreting them differently?) in my
testing. However, in the process it led to a fix of a secondary color handling
issue where it would be taken from the wrong offset, I believe, based off of
reading the r200 driver. Also add a minor tweak to save time in the
fog-but-not-specular case.
width and height stayed the same. Rely on front.offset pointing at the origin
in the window (rather than the origin of the front buffer), and fix the coords
in swapbuffers, which were wrong. This is different from other drivers because
we've got a back buffer with a 0,0 origin at the window's origin, which makes it
more convenient to have the front buffer match it.
last drop I saw, which was in turn based on a code drop of mine. Texturing,
culling, and several extensions are unimplemented, and some features could
probably be improved. It's untested, but there don't appear to be regressions on
the 300-series code, so I'd like to get these bits in now so that it can be
worked on as not a huge diff.
wouldn't get confused when adding support for new formats. However, it resulted
in dying in texenv instead of drawing something undefined for GL_DECAL. Do what
GLcore apparently does and just pass the fragment through.
ones require custom texstore, so they aren't done yet.
- Add YCBCR support commented out, since the yuvsquare test didn't work with
just the bits I've added.
- Add the no-compression GL_ARB_texture_compression support.
- Add the driconf texture depth option and try to respect it.
tested using texwrap, fixing the sourcing of border constant values (use the
bytes, not the floats!). Remove the fallback on GL_CLAMP_TO_EDGE, which acts
properly, and add a note to GL_CLAMP about nonconformance (whcih is what the
fallback for CLAMP_TO_EDGE was probably targeting).
the register header was meaningful. It turns out those were the proper values
for the plain INCR/DECR ops, while what we were using as INCR/DECR were the
_WRAP versions. Tested with stencil_wrap (didn't expose normal/_WRAP swapping)
and stencilwrap (exposed it nicely) tests. Props to idr for poking me about
adding this.
"fall" so far) and make the fallback_force option be no_rast like other drivers.
Incidentally, makes no_rast not crash (though it still fails to render).
drirenderbuffers pointed at screen offset 0 and NULL. Instead, set up the front
buffer at startup but leave the others for later, since sis allocates them on
demand rather than using the static method of the other non-sis-descendent
drivers. Some basic apps work, but fallbacks may be broken still.
