It's a small rendering tool that takes commands from stdin.
You pipe the commands to the shiny-pancake executable. You can use the --size WIDTHxHEIGHT and --title TITLE command line parameters to change the window size and title.
It listens for a few commands on its standard input, these commands are:
#RESET Reset the draw state.
#COLOR <R> <G> <B> <A> Set the current drawing color to (R, G, B) and the alpha to A.
These are all unsigned integers with values from 0 to 255.
#RECT <X> <Y> <W> <H> Draw a rectangle at (X, Y) with size (W, H).
#CIRCLE <X> <Y> <RADIUS> Draw a circle at (X, Y) with radius RADIUS.
#ELLIPSE <X> <Y> <W> <H> Draw an ellipse at (X, Y) with size (W, H).
The commands are all case-insensitive. Every line that is not prefixed with any of the commands is ignored.
