The LOD is computed from texcoord partial derivatives and used to
select a mipmap level. Still some bugs in texel fetching. Lots of
rough edges and unfinished parts but the basics are in place.
Lots of changes to the lp_bld_arit.c code to support non-vector/scalar
datatypes.
ws/xlib: remove self-knowledge about users of xlib winsys
Several software rasterizers can make use of this winsys, but there
isn't any reason why the winsys itself should know about them.
This change moves that information into the libgl-xlib target.
Need to fix up other targets making use of this winsys.
cell: untwiddle surface contents in flush_frontbuffer()
Don't make the shared software winsys rely on internal knowledge about
the cell driver's texture twiddling.
This is just a sketch and hasn't even been compile tested.
gallium: don't use flexible array members in drivers for vertex elements cso
While this c99 feature should work with most compilers, valgrind doesn't
really like it, and this only really saves some memory, we don't do this
in similar occasions (like the blend state) neither.

gallium: remove p_screen::surface_buffer_create
This isn't very useful without texture_blanket(), which has also been
removed.
Note that this function hasn't been removed from the old pipe_winsys
(u_simple_screen) still used internally by some drivers (eg softpipe).

gallium: remove texture blanket call
No longer needed, except for nouveau and egl/xll/native_ximage.c.
Fix for nouveau is to keep the call, but move it to an internal
function within nouveau.
Fix for that egl/x11 relies on gallium-sw-api branch or its successor.

llvmpipe/gallivm: checkpoint: array of pointers to mipmap levels
Change the texture data_ptr from just a single image pointer to an
array of image pointers, indexed by mipmap level.
We'll use this for mipmap filtering.
For now, the mipmap level is hard-coded to zero.
i965: Fix up the handling of point sprite coordinate replacement.
The code was walking over the regs of pairs of attributes and checking
whether the attribute with a given reg index had point sprite enabled.
So the point sprite setup code was rarely even getting executed.
Instead, we need to determine which channels of a reg need point
sprite coordinate replacement. In addition, it was multiplying the
attribute by 1/w, when it's supposed to cover (0, 1) in each direction
regardless of w, and it wasn't filling in the Z and W components of
the texcoord as specified.
Fixes piglit point-sprite and the spriteblast demo. Bug #24431, #22245.
