Ensures draw is a no-op prior to pipeline setup.
2019-03-03 15:04:14 -05:00
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.

6b4f6971de
Disables upper limit on frame buffer size.
...
Filtering is sufficiently imperfect as to make this justifiable only when performance requires it. So I need a test for that. Marked as TODO.
2019-02-26 22:39:07 -05:00
79707a3c66

7bb90c78d9
Resolves out-of-bounds initial condition whenever this loop began with start_line = 2047.

This, I believe, was the remaining cause of screen flashes.
2019-02-24 19:50:19 -05:00
a6e61ef83b
Reverts the clear colour to black.
...
The change was related to debugging; it was not intentionally committed.

2019-02-17 21:49:53 -05:00

2019-01-05 23:09:17 -05:00
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
