[Decompilation] [th01] 8×8 diamond, star, and snowflake sprite blitting More hardcoded sprites! These are prominently seen in the Konngara, Elis, and Sariel battles, respectively. Completes P0105, funded by Yanga.

// Blits the hardcoded diamond, star, or snowflake sprites in the given [col]
// to the given position.
[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.

[Decompilation] [th01] Ellipse arc blitting Most frequently used for complete circles, though… but who cares, as of this commit, ReC98, as a whole, is ⅓ done! Part of P0120, funded by Yanga.

[Maintenance] [th01] Merge invincibility sprites into the regular 8×8 shapes They have the same size, their hardcoded sprites are stored next to each other in the code, and… Part of P0153, funded by Ember2528.

[Maintenance] [th01] Use a common macro for sloppy unblitting of 8×8 sprites … treating them as conceptually the same thing allows us to deduplicate these macros. Part of P0153, funded by Ember2528.

[Maintenance] [th01] Wrap EGC rectangle copies with 16-bit-aligned widths Consolidating the associated "WTF" and "I don't even" and "lol ZUN" into one place. Part of P0158, funded by Yanga.
