Made TIA window always open at a multiple of the minimum bounds

- this means that 320x240 is now the default 'base' size, and zoom levels are based on that
- the TIA image is rendered into whatever sized window is active, meaning that NTSC and PAL modes now look similar

Removed some 'small screen' dead code in FrameBuffer.
