Copy I420 with optional flipping. TODO(fbarchard): Use Scale plane which supports mirroring, but ensure is does row coalescing.

Convert I420 to RGB565 with specified color matrix.

422 chroma is 1/2 width, 1x height 420 chroma is 1/2 width, 1/2 height

444 chroma is 1x width, 1x height 420 chroma is 1/2 width, 1/2 height

Convert NV21 to ARGB with matrix

FIXME-LEGACY: Prior to 1.61 our DragInt() function internally used floats and because of this the compile-time default value for format was "%.0f". Ev

Reserve space for a number of vertices and indices. You must finish filling your reserved data before calling PrimReserve() again, as it may reallocat

Old 7 bit math for compatibility on unsupported platforms.

Simplify the filtering based on scale factors.

Support function for NV12 etc UV channels. Width and height are plane sizes (typically half pixel width).

Support converting from FOURCC_M420 Useful for bandwidth constrained transports like USB 1.0 and 2.0 and for easy conversion to I420. M420 format desc

C reference code that mimics the YUV assembly.

C reference code that mimics the YUV 10 bit assembly. Reads 10 bit YUV and clamps down to 8 bit RGB.

Reads 8 bit YUV and leaves result as 16 bit.

Initialize before use in a new frame. We always have a command ready in the buffer.

Copy ARGB with optional flipping

TODO(fbarchard): Improve sign extension/packing.

Convert 32 ARGB pixels (128 bytes) to 32 Y values.

Convert 16 ARGB pixels (64 bytes) to 16 YJ values. Same as ARGBToYRow but different coefficients, no add 16, but do rounding.
