24// //
25// Unfortunately, TGCocoa's drawing methods can be called in a //
26// "wrong" time and place: not from QuartzView -drawRect. //
27// For example, on mouse move. This is bad and unnatural for Cocoa application, //
28// since I expect GUI to draw only when I'm ready == ... called from drawRect. //
29// In X11 commands are buffered and this buffer is flushed at some points. //
30// I'm trying to emulate this, just to make GUI happy. //
