Hi!

1. I searched info/tutorial/etc. about how to draw 2D/3D graphics in RHO. I can't install glu/glut only the newest opengl on ruby 1.9.3 so i suppose that it's not possible to draw by opengl but maybe it's another way? Of course I'm not mean draw by html5 (canvas) becouse performance it will be the some (I think) such in another software like Cordova etc.

2. It's image manipulation posible? For example applying filters to images, search red objects on image?
