This refactors
_set_pixel
function into its two main functions, updating the dirty area and writing the pixel. This allow reuse of the_set_dirty_area
and_write_pixel
with other bitmap manipulation functions (and providing a minor speedup to_blit
).I updated the
_blit
function to use these new sub-functions.
