Emulator

The software gfx backend got broken when merging the plugins. Since it's a very important reference of the hardware behavior, it should have been fixed ages ago, but no one did. This really needs to be looked into until 3.0.

From what I gathered it shouldn't be too hard to fix it, Billiard probably can be asked about what needs to be done.

Not sure which platforms this affects, but at least Video_Software doesn't get built on Windows.
