Instead of having special cases at each GL texture creation, upload, readback or copy for all non-8-bits-per-components. Simply store the more specific format and retrieve the generic component/type tuple from that. Introduce a helper function for retrieving the generic GL format (RGBA, RGB, RG, R, L, A) and type (BYTE, SHORT, SHORT_5_6_5) from a sized GL format enum (RGBA8, RGB565, RG8, etc).
