[Cuis-dev] FYI. VectorGraphics freezes World. CuisBook procedure.

[Juan Vuletich]

The truth is that all I need to move to the Canvas is the specific 
methods to draw the icons in window controls. There are Form in 
BitBltCanvas, but just drawing calls in VectorGraphicsCanvas. Let my try 
to partially revert the changes, and see if I can get VG drawing the 
icons, without reducing the flexibility you need.

Thanks,
