Just a Basic Pie Chart Maker

Uses a TListbox to enter the values into.

Made the following changes:

Added labels for labeling the values on the chart.
These label positions can be changed with mouse click and drags.

Dynamically placing these labels when the font size of the labels is
changed.
I made the centroid of the Value labels move along radial mid-lines of
each sector.

Saving the labeled values on the Pie Chart to png.
Thanks to ( https://stackoverflow.com/questions/43738888/save-
imageenview-and-a-label-on-it-as-png-in-delphi ) for the idea on how
to do it.

Enjoy.

Actually had an idea of using a TColorListBox instead of a Normal
TListbox.

but things are kinda getting real screwed. Ouch!
