-// The Direct2D scratch window is a utility for libui internal use to do quick things with Direct2D.
-// To use, call newD2DScratch() passing in a subclass procedure. This subclass procedure should handle the msgD2DScratchPaint message, which has the following usage:
-// - wParam - 0
-// - lParam - ID2D1RenderTarget *
-// - lResult - 0
-// You can optionally also handle msgD2DScratchLButtonDown, which is sent when the left mouse button is either pressed for the first time or held while the mouse is moving.
-// - wParam - position in DIPs, as D2D1_POINT_2F *
-// - lParam - size of render target in DIPs, as D2D1_SIZE_F *
-// - lResult - 0
-// Other messages can also be handled here.
