2d76132a8b Constrain the Gravis UltraSound's playback frequency selection 
The Gravis UltraSound emulator generates undistorted stereo output
at playback frequency of 11025 Hz and powers-of-two multiples greater,
such 22050 Hz and 44100 Hz.

At frequencies that are not multiples of 11025 Hz; such as
49716, 48000, 32000, 16000, and 8000 Hz; playback is distorted by
the addition of ringing and stereo separation is lost.

This commit constrains the configurable GUS playback frequencies
to 44100, 22050, and 11025 Hz.

It also corrects the spelling of "UltraSound", which was previously
spelled "Ultrasound".

5ed90b57eb Change 'render.aspect' default to 'true' 
We don't use surface output by default, so there's no point in keeping
square-pixels by default due to performance issues.

a2d1450246 Introduce a penalty for a lot of idling, which changes the up and downscale algorithm, as the chance of having errors in the input data is a lot larger when there is a lot of idling. The upscale has its strength reduced and the downscale has it increased.
