fbf1adef05 Introduces unit test and thereby seemingly fixes get_next_sequence_point. 
There's still improper output in the actual machine though, so maybe something else is afoot?
 2021-06-18 17:44:17 -04:00
Thomas Harte

Thomas Harte
d61f478a39 Basic sketch for state snapshots: an extra field on Target. 
I think it doesn't make sense for states to own a target as that complicates the concept of Media. Plus they're distinct because it makes sense to have only one per Target. Let's see how this pans out.

Thomas Harte
df89a8771c Makes an attempt to have the emulator fill the actual GPU buffers. 
Not that they're drawn from correctly yet. I might first take a run at a new quick-path output route for emulated RGB displays, that just seeks to use the scans directly. No intermediate buffers. Besides probably being a good feature, it'll be a good way to ramp further up with Metal.
 2020-08-08 22:49:02 -04:00
