I have a basic encoder finished. Merge?

Its not the full spec, but its 32 bit rgba TGA encoder.

I could merge it, but I'd better have encoding based on the source image itself, to do as little conversions/allocations as possible...

• Gray -> monochrome 8 bit
• NRGBA (non-premultiplied) -> plain RGBA
• RGBA (premultiplied) -> RGBA with attribute type set to "premultiplied"
• Palette -> tga with a colormap

[mortdeus]

My encoding only depends on image.Image. While at the moment its asserting the image is a RGBA, and redrawing it that way if it isnt, it is just a minor mod to support all the other different possible modes at that point.

I assume you are doing this for glfw?

Not exactly for glfw, but I'm also taking it into account.
