Defining Custom Views - getTrianglePath() allocating new Points/Path in onDraw()

[teotigraphix]

This is a no-no and it's not caught by the compiler(IDE) because it's in a caller method.

Just some best practices, especially for a custom view guide.

(If I had the time I would fix it but just wanted to note this.)
