1936e4bdfd cell: Initial code-gen for alpha / stencil / depth testing 
Alpha test is currently broken because all per-fragment testing occurs
before alpha is calculated.

Stencil test is currently broken because the Z-clear code asserts if
there is a stencil buffer.

0c715de39f cell: Fix simple register allocator 
THere are 64-bits in a uint64_t, not 128.  Duh.

5456f4f210 mesa: new mipmap generation, lod bias demo 
Show each of the mipmap levels side-by-side.
Press 's' to toggle quad scaling to see mipmap level at actual size.

f1b42595d0 gallium: new mipmap generation code 
Based on code from Mesa's state tracker.
Still need to implement fallbacks for those texture formats which can't
generally be rendered to.

9425a702be gallium: improvements, or extensions at least, to the passthrough path 
Passthrough is actually more tricky than you'd think...

49a687882a gallium: finish remaining prim types for sp_vbuf_draw_arrays() 
Not totally tested, but easily fixed if glitches are found.

cbf42c45a1 gallium: if point size not computed per vertex, apply size clamp immediately. 
Fixes glean pointAtten failure.

New draw_enable_point_sprites() function.

7dc449d406 mesa: fix emit_clamp() so that we don't use an output register as temporary 
IR_CLAMP is decomposed into OPCODE_MIN+OPCODE_MAX.  Allocate a temporary
register for the intermediate value so we don't inadvertantly use an output
register (which are write-only on some GPUs).

14150bc856 mesa: call glColorMask(1,1,1,1) before glClear() 
Without this, second and subsequent redraws rendered incorrectly.
Plus comments.

9de9e1fe8c gallium: print warning rather than assert(0) for LOG/EXP opcodes 
Glean vertProg1 runs all the way through, rather than aborting.

c45a525cdc mesa: revert fast-track glColor and similar calls when not immediate mode rendering 
Revert commit d08cd68d3f

This change caused some glean tests to fail.  The alpha value of colors was
always 1.0 instead of the value from glColor4fv().  The mesa color array
found in st_draw() has size=3 instead of size=4.

ee55eaa609 gallium: in st_program_string_notify() free shader tokens. 
When the shader instructions change, free the TGSI tokens.  This signals the
state tracker to recompile the shader.  Fixes a regression caused by recent
shader/state-tracker changes.

78302c7ca3 gallium: need to all draw_flush() in softpipe_unmap_constant_buffers() 
Otherwise, we won't have our constants when we run the fragment shader.
Fixes crash in glsl tests when SP_VBUF=1.

d088d640fc gallium: plug in vertex passthrough code 
Based on a patch from Zack.
Basically, implement a new draw_arrays function that copies the incoming
user-vertices to the hardware vertex buffer, doing format/type conversion
as needed.
The vertex fetch/store code is totally temporary for now.

5bae5871f0 gallium: for TEST_DRAW_PASSTHROUGH, pass inClipCoords=FALSE to st_draw_vertices() 
When pass-through mode is fully supported we'll clean this up more.

269fbeb545 gallium: in softpipe_get_vertex_info() generate a vbuf vertex_info with real attribs 
Can't use the EMIT_ALL shortcut/optimization anymore because of passthrough mode.

Brian
b9518a4e39 gallium: added new EMIT_HEADER token 
Used to emit the struct vertex_header info for softpipe.
Before we were using the EMIT_ALL token but that's insufficient for the
draw pass-through mode.  EMIT_ALL might get removed soon...

7d5e38a55a gallium: plug in new sp_vbuf_draw_arrays() function 
Will be used for pass-through mode.
Also, call draw_set_render() to register the vbuf stage.  Should probably
rename that function to something like draw_set_vbuf_stage().

3e625ce18e gallium: add some temporary code for testing draw module vertex passthrough 
Set TEST_DRAW_PASSTHROUGH=1, run progs/trivial/clear-scissor

Brian
69c39b9ae2 gallium: set surface status to CLEAR or DEFINED in clearing/drawing code. 
Otherwise, we were never setting these flags.  This confused the state tracker.
Fixes progs/demos/texenv.c, probably others.

3faf6230ff gallium: added draw_need_pipeline() predicate function 
To test if we need any pipeline stage, or whether we can go into passthrough mode.

8b8c9acdb7 gallium: added draw_enable_line_stipple() function 
Allows drivers that implement line stipple to turn off this drawing stage.
