720aba3f2d
Adds an implementation of SBCD and slightly neatens syntax for building programs.
2019-03-14 21:22:02 -04:00

f9101de956
This might very well be the 68000's first real gasp: performing an ABCD.

86a6b04d4a
Begins attempts to keep track of display metrics.
...
i.e. a system that can both make smart decisions about when to use a lower resolution, and hopefully allow some sort of flywheel-esque horizontal retrace synchronisation. And possibly some raster beam chasing?

On the Mac, draw is now called without an update for resizing events, and
anything else requested by AppKit. In all other cases — including from
the SDL version — both are called as if they were still a single function.
