Controls the how the pixel color is determined from a texture querying the texture coordinates are
outside the usual bounds.
• ALLEGRO_BITMAP_WRAP_DEFAULT - The default behavior. This corresponds to ALLEGRO_BITMAP_WRAP_REPEAT
when using the primitives addon and ALLEGRO_BITMAP_WRAP_CLAMP otherwise.
• ALLEGRO_BITMAP_WRAP_REPEAT - The texture coordinates get shifted to the opposite edge that they go
past.
• ALLEGRO_BITMAP_WRAP_CLAMP - The texture coordinates get clamped to the edges that they go past.
• ALLEGRO_BITMAP_WRAP_MIRROR - The texture coordinates get mirrored across the edges that they go past.
