2D picture control performance

[Darren]

Here's an old nugget post where I talk about this topic.

tl;dr - For best performance, turn off 'Erase First', and only redraw the parts of the image that have changed.

This kind of stuff should be done directly with the image data. Thats fast and does not increase memory usage.
