Description
Currently there is no facility to invalidate partial regions of the target HWND.
Please consider passing along the ClipRectangle from the PaintEventArgs here:

Research direction
Start in src/D2DWinForm/D2DControl.cs around line 100 and inspect how OnRender receives PaintEventArgs. Trace how the ClipRectangle could reach partial invalidation of the target HWND, then verify that the rendering path uses the requested region. Done means partial target regions can be invalidated through OnRender.
