tgsi: add properties for fragment coord conventions (v3)
Changes in v3:
- Documented the new properties
- Added comments for property values
- Rebased to current master
Changes in v2:
- Caps are added in a separate, subsequent patch
This adds two TGSI fragment program properties that indicate the
fragment coord conventions.
The properties behave as described in the extension spec for
GL_ARB_fragment_coord_conventions, but the default origin in
upper left instead of lower left as in OpenGL.
The syntax is:
PROPERTY FS_COORD_ORIGIN [UPPER_LEFT|LOWER_LEFT]
PROPERTY FS_COORD_PIXEL_CENTER [HALF_INTEGER|INTEGER]
The names have been chosen for consistency with the GS properties
and the OpenGL extension spec.
The defaults are of course the previously assumed conventions:
UPPER_LEFT and HALF_INTEGER.
