OpenEuphoria

1. Need Help with Musubi Demo

I have created a demo for wxEuphoria that provides a benchmark for graphics primitives. I'm wanting to port it to a demo for SDL/Musubi (from Mark Akita), but it's having memory issues. I'm posting the program below in case anybody can help.

In the original demo, buttons were used to toggle drawing on/off. With this Musubi demo, I'm just using keystrokes.

Of course, you'll need Mark Akita's Musubi package (don't know if that is cross-platform).

I appreciate any help I can get on this.
