Integer types support in Blitter
The blitter now supports integer types. This means:
- It supports conversions to/from integer types from/to
other already supported types.
- It supports integer to integer conversions without going
to an intermediate float format.
Also added a Blitter::GetScale() function to avoid having
2 instances of the same switch statement in the code and
added the read/write utility functions. The final Blitter
code is not longer peppered with switch statements and is,
hopefully, easier to read that way.
