Thomas Harte
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?

bee0d09877
Splits display update and draw functions.
...
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.

46d756d298
Starts towards a flattening of the intermediate video processing.
...
Immediate issue: using x position to index into a bitmap sampled at the input data rate doesn't allow for the disconnection between input rate and output speed provided by the flywheels.
2019-01-05 18:11:39 -05:00

Attempts an initial flattening of the pipeline, seemingly losing all output.

Moves pipeline setup into draw(), where there'll definitely be an OpenGL context.

16dfeb3fc8
Discards empty lines, yet makes some attempt at restoring transparency.

dce52d740d
Finally gets some pixels back on screen.
...
For now, just the raw scans, direct to the framebuffer, with no intermediate processing. But it seems to prove that at least some of the proper data is reaching the GPU.
