Depending on whether vgDrawPath(mode), vgDrawImage, or vgDrawGlyph[s] is
called, different paint-to-user and user-to-surface matrices should be
used to derive the sample points for the paint.
This fixes "paint" demo.
Divide bits of VegaShaderType into 6 groups: paint, image, mask, fill,
premultiply, and bw. Each group represents a stage. At most one shader
from each group will be selected when constructing the final fragment
shader.
Optional features such as auth-hinting are not implemented. There is no
anti-aliasing, and no effort is done to keep the glyph origin integral.
So the text quality is poor.
With this commit, the pipe states are entirely managed by the renderer.
The rest of the code interfaces with the renderer instead of
manipulating the states directly.
st/vega: Delay fb state update to vg_validate_state.
vg_manager_validate_framebuffer should mark the fb dirty and have
vg_validate_state call cso_set_framebuffer. Rename VIEWPORT_DIRTY to
FRAMEBUFFER_DIRTY.
st/vega: Add POLYGON_STENCIL and POLYGON_FILL renderer state.
The states are designated for polygon filling. Polygon filling is a
two-pass process utilizing the stencil buffer. polygon_fill and
polygon_array_fill functions are updated to make use of the state.
This state provides the ability to clear rectangles of the framebuffer
to the specified color, honoring scissoring. vegaClear is updated to
make use of the state.
This state provides glDrawTex-like function. It can be used for
vgSetPixels.
Rather than modifying every user of the renderer, this commit instead
modifies renderer_copy_surface to use DRAWTEX or COPY state internally
depending on whether the destination is the framebuffer.
Renderer states are high-level states to perform specific tasks. The
renderer is initially in INIT state. In that state, the renderer is
used for OpenVG pipeline.
This commit adds a new COPY state to the renderer. The state is used
for copying between two pipe resources using textured drawing. It can
be used for vgCopyImage, for example.
Rather than modifying every user of the renderer, this commit instead
modifies renderer_copy_texture to use the COPY state internally.
gallivm/llvmpipe: squash merge of the llvm-context branch
This branch defines a gallivm_state structure which contains the
LLVMBuilderRef, LLVMContextRef, etc. All data structures built with
this object can be periodically freed during a "garbage collection"
operation.
The gallivm_state object has to be passed to most of the builder
functions where LLVMBuilderRef used to be used.

I made the texwrap test be more thorough and realized that this driver code
had not been quite right. This commit fixes the border color for depth
textures, compressed textures, and 16-bits-per-channel textures
with up to 2 channels (R16, RG16).
NOTE: This is a candidate for the 7.9 branch.
u_blitter: interpolate clear color using a GENERIC varying instead of COLOR
There are also some u_simple_shaders changes.
On r300, the TGSI_SEMANTIC_COLOR varying is a fixed-point number clamped
to the range [0,1] and limited to 12 bits of precision. Therefore we can't
use it for passing through a clear color in order to clear high precision
texture formats.
This also makes u_blitter use only one vertex shader instead of two.
Since the viewport is not updated on RandR12 mode switches anymore,
clipping to viewport may incorrectly clip away the video.

xorg/vmwgfx: Flush even if we don't autopaint the color key
This may help paint the colorkey before overlay updates in some
situations where the app paints the color key (mainly xine).
