to more easily scale halves/quarters etc of a circle than possible with the ones that take 0..255 'degrees'.

eea3fb48a8 add command line option 'optfloatx' to explicitly re-enable float expr optimization as this can increase code size significantly.
The output size of the various example programs using floating point, when not using this optimization, has been reduced significantly.
The resulting code runs a (tiny) bit slower though.
