The chars-per-pixel concept falls apart with compressed and yuv images,
where more than one pixel are coded in a single data block.

This is step towards tiled textures and buffer support for
i915. But the tiled attribute is never set.
|
|
All offsets are now on image_offset.

The later follows the naming scheme of other limits.
Keep the old definition until all possible usage is updated.

Bind all the samplers/textures at once rather than piecemeal.
This is easier for drivers to understand.

This will allow creating textures before a rendering context exists, for example.
Only implemented in i915 driver for now. i915pipe->texture_create() just
dispatches through to the i915screen->texture_create() to avoid state tracker
changes for now.

No longer use semantic info in pipe_shader_state.
Also, remove redundant semantic info from i915_fp_compile struct.

Before, fragment shaders were translated to i915 hw code at bind time, rather
than create time. Now there's an i915_fragment_shader struct with the expected
contents that's created by i915_create_fs_state(). Translation to i915 code
takes place there too.
Immediates are handled correctly now. During program translation we keep
track of which constant buffer slots are free (i.e. not referenced by the
shader). Then the TGSI immediates and ancillary immediates (introduced for
SIN/COS/etc) are put into those free slots.
When it's time to upload the constant buffer, use the fp->constant_flags[]
array to determine if we should grab an immediate from the shader, or a
user-defined parameter from the gallium constant buffer.

Update the Makefiles and includes for the new paths.
Note that there hasn't been no separation of the Makefiles yet, and make is
jumping all over the place. That will be taken care shortly. But for now, make
should work. It was tested with linux and linux-dri. Linux-cell and linux-llvm
might require some minor tweaks.

This is in a separate commit to ensure renames are properly preserved.
