Detailed Description
cDrawer class.
A cDrawer derived class behaves like a Filter and extends its functionality by IDrawer methods, a Draw method and the coordinate space handling.
A cDrawer shares the Canvas with the containing Filter (based on cFilter) and handles Mouse and Keyboard events.
If the parent property is set, then the coordinate space is placed inside the referenced coordinate space. The parent property can contain the name of any drawer instantiated in the current filter graph. If no parent is set, the 2DDisplay coordinate space aka world is the parent.
