[Maintenance] [th01] Add a header for the slow 2× rectangle scale function Part of P0094, funded by Yanga.
2020-05-20 11:54:38 +00:00
// Performs a very slow, unoptimized, 2× nearest-neighbor scale of the
// rectangle from
// (⌊left_1/8⌋*8, top_1) - (⌊left_1/8⌋*8 + ⌊w_1/16⌋*16, top_1 + h_1)
// on plane #1 to
// (⌊left_0/8⌋*8, top_0) - (⌊left_1/8⌋*8 + ⌊w_1/16⌋*32, top_1 + h_1*2)
// on plane #0.

[Maintenance] Declare distinct types for screen, VRAM, and TRAM coordinates Whew, time to look at every `int` variable we ever declared! The best moment to do this would have been a year ago, but well, better late than never. No need to communicate that in comments anymore. These shouldn't be used for widths, heights, or sprite-space coordinates. Maybe we'll cover that another time, this commit is already large enough. Part of P0111, funded by [Anonymous] and Blue Bolt.
