TINYGL: Deduplicate PixelFormat retrieval in zblit

Browse source 
For some reason, loadData hardcodes a pixel format.
At least avoid duplicating it in Line constructor.
Likewise, avoid duplicating access to framebuffer's pixel format when
constructing a Line from another.
Also, avoid over-allocating Line, as its size argument is counted in pixel,
not in bytes.
