Improved ground overlays: performance, transluscency, visibility

-Performance improved by replacing object construction in critical part of the code with static calls
-Added transluscency based on alpha of pixels in overlay icon
-Added testing for global visibility before rendering overlay

Ran with several images of ground overlays, tested performance with QElapsedTimer.

All three aspect work and the performance is improved almost 3x on my machine - tested by rotating and moving the overlay around.
