* 4f linear gradient shader blittersGravatar fmalita2016-03-18
| | | | | | | | | | | | Add F16 specializations to support writing to half-float dests. Add color profile template arg across the board to support writing to sRGB dests.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These are basically inlined, 4-at-a-time versions of our existing functions, but cut down to avoid any work that's only necessary outside [0,1]. Both f16 and f32 denorms should work fine modulo the usual ARMv7 NEON denorm==zero caveat. In exchange for a little speed, f32->f16 does not round properly. Instead it truncates, so it's never off by more than 1 bit. Support for finite values >1 or <0 is straightforward to add back. >1 might already work as-is.
