Purpose
Overlay a picture on another and allow the user to drag it quickly.
Method
Use a hidden PictureBox to store the background image. To move the
foreground object, erase it using BitBlt to draw from the hidden picture
to the visible picture. Use BitBlt and the image mask with op code
MERGEPAINT to knock out the mask. Finally, use BitBlt with the foreground
image and opcode SRCAND to drop in the foreground image.
