Made a Fractal Tree out of an array of polygon points in the shape of
trapeziums.
Rendering using a TBgrabmp and a TPaintbox.

Got the idea from
https://www.codeproject.com/Articles/5269971/Fractal-Tree-with-Lines-
Polygons-Written-in-Java
Fractal Tree with Lines/Polygons Written in Java By Marijan Nikic  

Made the initial trunk in the shape of a trapezium (the java version
just had a rectangle).

Noticed at higher thickness levels I am not getting exact alignment at
the edges of the V branch meeting points.

Also needed to do  SetLength(newStartPoints,
System.Length(newStartPoints) + 1);

instead of SetLength(newStartPoints, Length(newStartPoints) + 1);

Not exactly sure why System. was needed if I have uses SysUtils

Also notice the Java version has better defined top level line
branches (see attached png of Java version). I needed to increase the
thickness to get those lines being more defined in the Lazarus
version.
