2021-09-26	Of course i didn't need i32 ...	tslil clingman

2021-09-22	There was really no reason to use a BoundedArray instead of an array	tslil clingman

2021-09-22	Switch to more accurate version	tslil clingman
	Pre-emptive micro-optimisation is bad. There aren't that many sprites pixels usually anyway.
2021-09-22	Colour blending	tslil clingman
	Some amount of work went into finding appropriate integer arithmetic formulae that were reasonably accurate. At this point i've settled for the incorrect-but-faster version. The better-though-slower formulas are still there in case i change my mind. It would help to have an assumption such as, but not limited to, the surfaces are always going to be fully opaque.
2021-09-20	Render objects by writing pixels	tslil clingman
	This confines hardware acceleration to scaling and the background sprite. Unfortunately it would seem that to do proper object rendering (partial transparency) i'll have to implement colour mixing myself.
2021-09-20	Corrected rendering bug	tslil clingman

2021-09-20	Render walls by pixels, instead of using hard. accel. sprites	tslil clingman
