Thomas Harte
35f1a7ab10
Resolves a potential out-of-bounds array access.
...
Risk was: allocation exactly joins end of buffer. In which case the next get_data won't wrap the texture y coordinate since it won't spot an x overage.

4266264449
Switches to the more idiomatic .empty().

6f7dd10d95
Reduces draw/update contention.
...
This won't yet have any effect on either port owing to the way they handle contexts, but here it is.

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?
2019-03-04 21:54:50 -05:00

Thomas Harte
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.

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
Thomas Harte
a6e61ef83b
Reverts the clear colour to black.

2019-02-17 21:49:53 -05:00
Thomas Harte
008f50832c
Fixed: the two shaders that use a common input array should use common bindings.
2019-02-10 22:39:24 -05:00

With a little more debug logging, discovered an issue with incrementing by four.
