* Each exercise sprite given its own texture sheet to reduce texture swaps which tax game performance.
+ various code optimisations.

I am really hoping that this patch may make a dent in the blue bar stopping short glitch. bytor11 and Crafozura have given me some really useful extra information which clearly points to sprite loading strain being at the heart of slowing down the blue timing bar/exercise causing a time lag.

I have another update planned if this doesn't work where I will try to halve the sprite loading strain even more in all algorithms (I will still do this regardless of whether this patch update works or not).

Thank you for being so patient. Fingers crossed that this patch may help.
