Switch to 59.94 fps rather than 60, since we say we are 59.94

This fixes #4040, and the games I tested still seemed fine.  Star Ocean still okay too (no enemies soaring to the stratosphere still.)

Having hcount be an integer also improves the accuracy in the hcount test, matches the way games seem to calculate around it, and makes more sense anyway.

Might break games but seems to match tests.
