Detailed Description

The uncompressed-BGRA codec (ColorEncoding::Bgra / BgraAlt): a pure channel swizzle.

Stateless, a class for symmetry with the other codecs and to keep the swizzle off the free-function surface.

Decode one level's BGRA bytes to RGBA8 pixels.

Parameters

src	the on-disk BGRA bytes; short payloads decode their missing texels transparent black.
width	the level width in pixels.
height	the level height in pixels.

Returns

width * height * 4 RGBA bytes.
