[Lazarus] FPVectorial and TAChart

[Alexander Klenin]

I have tried to use FPVectorial as TAChart back-end.
So far, without success.
I have a few questions/feature fequests, sorted approximately
by decreasing importance:

1) How to draw a rectangle?
2) How to measure a text?
3) How to draw a polygon?
4) How to make FPVectorial output anything?
  It seems crash no matter what output format I try.
5) IMHO intruducing yet another color type is a bad idea --
FPVectorial is by design sacrificing efficiency in favor
of generalization/extensibility, so I do not think a few extra bytes
for color will matter. Please use TFPColor.
6) How to draw a radial pie?
