added ARCANGLETO command implementation, optimization, fixes, debug
- added new ARCANGLETO command needed for PPTX custom shapes import
- added added placeholder for unimplemented QUADRATICCURVETO command,
skip it's data at least so that we don't break other things for now
- cache equations results to optimize custom shapes calculation
PPTX import creates such equations that made system busy for long
time, this removes that issue
- added lot of debug output to help with debugging of complex imported
custom shapes
