Codechange: [Blitter] Change DrawLine to be templated

Browse Source 
This is remove per-pixel overheads due to use of the SetPixel virtual

These overheads included:
* expensive virtual method call which prevents inlining
* palette lookup for every pixel
* branch on whether palette animation is enabled on every pixel
