Note that when shadowDrawing is true, shadowStipple may be either a color, for a solid shadow of the given color, or it may be a stipple used to simulate gray shading when the display cannot support alpha blending.

	copyClipRect:
	copyOffset:
	copyOffset:clipRect: Make a copy of me offset by aPoint, and further clipped by sourceClip, a rectangle in the un-offset coordinates
	copyOrigin:clipRect: Return a copy of this canvas with the given origin. The clipping rectangle of this canvas is the intersection of the given rectangle and the receiver's current clipping rectangle. This allows the clipping rectangles of nested clipping morphs to be composed.

	setStencilColor:form: Install a new color used for stenciling through FXBlt. Stenciling in general is done mapping all colors of source form to the stencil color and installing the appropriate source key. However, due to possible transparency we may have to install the color map as source map so that sourceForm gets mapped to a 32bit ARGB pixel value before the color combination is done. If we don't need translucency we can just use the regular color map (faster!)
