Queue a region, which is given in canvas coordinates, for drawing.
The view implementation is responsible, that this region is drawn, either immediately, or (which is more typical, since more efficient) the areas are collected, combined (as far as possible), and the drawing is later done in an idle function.

Called before drawing.
All actual drawing operations will be enclosed into calls of dw::core:View::startDrawing and dw::core:View::finishDrawing. They may be implemented, e.g. when a backing pixmap is used, to prevent flickering. StartDrawing() will then initialize the backing pixmap, all other drawing operations will draw into it, and finishDrawing() will merge it into the window.
