This change may end up being a bit slower on some systems, as the SDL backend will now render its content to two, new, SDL_Surfaces: one of which is in the guest OS' resolution, the other of which is application defined.
SDL2's SDL_Render API is used, which exposes some rudimentary elements of GPU + texture-based programming. Basilisk II now maintains a single 'SDL_Texture' object, which is an SDL representation of a GPU texture. The 'outer' surface will be used to update this texture, as requests to redraw are made.
TODO: look into removing the 'outer' SDL surface, and see if we can just copy the 'inner' surface to the SDL_Texture.
TODO: the entire SDL_Texture is updated, any time a request is made to draw. Look into minimizing this a bit.
This is useful for keeping the volume of SS/B2 separate from that of the host machine. For example, you can mute a game in SS, while still playing music on your host.
Add bin/cue support. The following should work:
1) Basilisk and SheepShaver with sdl-audio and bincue on linux and os x
2) SheepShaver with bincue and core audio on os x
This patch helps to keep the audio from breaking-up on slow machines when using
SDL audio. On those slow machines you do still get the break-up every so often
but the sound tends not to break-up nearly as often. It is much better on the
ears. Notably often the system beeps do not have a pause in them.
Slow machine is <= 1 GHz G4.
