Frank 5240c3450b Segment drawing optimizations (FASTPATH only) ...

* cache width, height, and a few more values that are normally re-calculated for each pixel
* make normal sPC a bit faster
* Segment::fade_out() optimization

--> only active in FASTPATH mode, to preserve flash on small devices (8266)
--> code still needs some polishing
--> up to 20% speedup with some 2D effects (esp32,  flash qio 80Mhz, -O2)
