The canvas other than PostscriptCanvas don't use the target, they are sinks.
That’s only technically true, and really an oversight. All canvases write their output somewhere, be it a bitmap, native display surface or other ‘DisplayMedium'. A canvas is a filter for converting morphs to this target ‘DisplayMedium’.
And having filter-canvases would be really cool :-)
You mean like ColorMappingCanvas, AlphaBlendingCanvas, and ShadowDrawingCanvas? (Which, by your account, should not have an own myCanvas but rather reuse target…)?
