Subject: mesa: Remove _mesa_rebase_rgba_uint and _mesa_rebase_rgba_float
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=769de5165c71315d66bab2bc27be98ec481ea9f8;p=mesa.git

mesa: Remove _mesa_rebase_rgba_uint and _mesa_rebase_rgba_float

These are no longer used anywhere now that we have _mesa_format_convert.

-/**
- * If we unpack colors from a luminance surface, we'll get pixel colors
- * such as (l, l, l, a).
- * When we call _mesa_pack_rgba_span_float(format=GL_LUMINANCE), that
- * function will compute L=R+G+B before packing.  The net effect is we'll
- * accidentally store luminance values = 3*l.
- * This function compensates for that by converting (aka rebasing) (l,l,l,a)
- * to be (l,0,0,a).
- * It's a similar story for other formats such as LUMINANCE_ALPHA, ALPHA
- * and INTENSITY.
- *
- * Finally, we also need to do this when the actual surface format does
- * not match the logical surface format.  For example, suppose the user
- * requests a GL_LUMINANCE texture but the driver stores it as RGBA.
- * Again, we'll get pixel values like (l,l,l,a).
