I was waiting for the need to use this code to arise, and it finally came.
I've tested building this on Linux and Windows, both x86 and x64_64. But
it might break other platforms. Please bear with me and help me fix it.
Many thanks to Dennis Smit who submitted this, and Eric Anholt whose
work this was based on.

This has several advantages over the u_
- not hand written
- no intermediate memcpy of raw pixels
- supports 4 ubytes in addition to floats
- no need to pass a pipe_transfer
It also has (hopefully temporary) limitations:
- no support for YUV
- no support for SRGB

There are some inconsistencies in pipe_format, but above all, there
simply aren't enough bits in an enum to conveniently store all
information about a pixel format we need to be able to dynamically
generate pixel packing/unpacking code.

Use these for quickly creating an RGBA drawing surface.
|
|
Nice for stack backtraces.
Windows-only for now.

|
Add a module that will manage uploading and coalescing multiple
user-buffers, malloc-buffers and other random data that doesn't
happen to be in a GPU buffer already. The module stuffs multiple
little uploads into larger GPU buffers to reduce create/destroy
overheads, etc.

The template makefile that most libraries in
gallium included was based on dri and had a bunch
unrelevant junk in it.
Update it and improve the depending makefiles.
|
|
The debug functions depend on several util function for os abstractions, and
these depend on debug functions, so a seperate module is not possible.

forwards screen calls to the winsys

Fixed size hash table. Collisions are handled by simply destroying the
previous entry.
It hasn't received much testing yet.

Also, rename p_tile.[ch] to u_tile.[ch]

So far, optimized/low-precision versions of exp(), exp2(), log2(), pow().

Copy rectangular region from one surface to another w/ scaling.
Disables most fragment operations.

frontend to cso_hash.

Don't define ASM_SOURCES variable globally -- reserve that variable to be defined
locally by makefiles, together with C_SOURCES and CPP_SOURCES.
|
|
Using the u_ prefix to distingish the c source files that support gallium
interfaces and those that have really no relation with gallium itself.
|
|
In other words, don't build src/gallium source code from within src/mesa/Makefile.
Also, allow to customize which gallium auxiliary dirs, driver driver, winsys
dirs get built from the config/* files.
