- Blitting the frame buffer works for 240p and 480p, though due to the usage of the scale-up values, some lines don't make it through in 480p. Additionally, something is wrong with 16-bit buffers.
- Running the window thread on the main thread since the main thread created the window. Windows isn't able to poll SDL events on a different thread.
- Disposing the SDL window on the thread which created it instead of relying on the finaliser to destroy it. Not doing so triggers a segfault as DestroyRenderer gets called. No need to destroy textures when disposing of the renderer as it does it.
- Display string for Point struct.
- Added SDL video output.
- Send VI interrupts when the currently scanned line hits the interrupt register's.
- Added some program options related to video.
- Manually restore execute bit on Unix.
- Use full paths everywhere instead of relying on current working directory.
- Less early returns on update operations.
- Formatting.
