Support unorm8x4-bgra in OpenGL / GLSL

This vertex format is not natively supported on OpenGL so a Tint option
is added to optionally swizzle vertex inputs from RGBA to BGRA. The
transform is done as part of ShaderIO by extracting the vertex input as
a vec4f before swizzling it and converting it to the original vertex
input type.
