A primitive may be splitted in frontends. The splitted primitives
should convey certain flag bits so that the decomposer can correctly
decide the stipple or edge flags.
This commit adds flags to draw_prim_info and updates the decomposer to
honor the flags. Frontends and middle ends will be updated later.

This changes r300_destroy_context() so it can be called
on a partially-initialized context, and uses it when
r300_create_context() hits a fatal error.
This makes sure r300_create_context() doesn't leak memory
or neglect to call r300_update_num_contexts() when it fails.

This fixes a potential bug if (has_hyperz) is false
(it would still init the atom as if has_hyperz were true).

Check for these and route them to a dedicated handler with one fewer
levels of recursive rasterization.

No need to calculate these values any longer, nor to store them in the
bin data. Improves isosurf a bit more, 115->123 fps.

For 16 and 64 pixel levels, calculate a mask which is linear in x and
y (ie not in the swizzle layout).
When iterating over full and partial masks, figure out position by
manipulating the bit number set in the mask, rather than relying on
postion arrays.
Similarly, calculate the lower-level c values from dcdx, dcdy and the
position rather than relying on the step array.

No noticable slowdown with isosurf.

isosurf 95->115 fps just by exchanging the two inner loops in this
function...

Per Jakob's request. Not super-pretty, but it's a good point for modding
later.

This skips the blitter clear path entirely if the color is not cleared and
the depth+stencil is cleared with the ZMask.

This commit silences the printing off most of the debug information
when running debug builds. The big culprits are: the tgsi sanity checker
that gets run on all shaders on debug; all the options; and
finaly the cpu caps printer.

This logic duplicates the one in p_config.h, so remove it and adjust
the only two places that were using it.

It causes a very ugly corruption on the Earth's halo on Google Earth.

This is based on a patch by nobled <nobled@dreamwidth.org> and allows the TFP
extension to be enabled for DRISW also. This patch does not enable TFP for DRISW
though, because testing on xephyr segfaults here (for both classic and gallium):
Program received signal SIGSEGV, Segmentation fault.
0x00786a4a in _mesa_GenTextures (n=1, textures=0xbfffee4c) at main/texobj.c:788
788 ASSERT_OUTSIDE_BEGIN_END(ctx);

The TFP code is generic except for the teximage call. We need to verify that
DRISW correclty implements whatever hook teximage finally calls.

It doesn't work well with Hyper-Z, so put the burden on the state tracker.

This always restores the previous depth clear value after CBZB clear.

These values are what fglrx returns.

It breaks Regnum Online in that it renders random triangles

I noticed gears memory usage was heading skywards, some r600 "states"
aren't properly refcounted, and the ctx->state is never freed.

Use a kludgy function based on rand() instead of drand48()
|
|
1. Generate random data specifically for float and doubles, so that
they end up in [0, 1] range
2. Don't test useless conversions like SCALED <-> NORM
3. Poison the buffers before testing

This takes the r300g texture format checker and fixes it up for r600g,
it passes glean texSwizzle, pixelformats, and texture_srgb tests,
however I think it L8S8_SRGB is broken as is L8_SRGB, need to investigate.

No need to enable depth test for clear.
