Use the mouse to draw and the keyboard to select a blending mode
A left click will draw a circle and prevent all previous drawing from being affected by new blending modes.
'a' = Over, 's' = Under, 'd' = Lighter, 'f' = Darker
During the creation of this tool several drawing modes were created both on perpose and by mistake.
These modes print different strings based on the selected blending mode or key press. You have the oppertunity of trying them all:
Regular | Number | Character | Undefined | Object | Blending Type
