[L2Ork-dev] Curious slowdown on a GOP array interaction

[Ivica Ico Bukvic]

... Curiously, as long as the array is not the top object, redraw is way 
faster. Even having a canvas that is on top of it in the gl_list (does 
not have to be above it visually, anywhere on the canvas),  makes things 
again super fast...
