1. Sprite Masking
Does anyone know how sprites using masks work?
Also how can I use Euphoria to draw them?
I am looking for alternatives to the simple:
if pixel_color = clear_color then
--Don't draw it
else
--Draw it
end if
This is slow because it requires that you cycle through
and examine each pixel in the image.

If you're using Win32Lib, you could use transBlt like this:
setTransparentColor({255, 0, 255}) -- bright pink is transparent color
transBlt(destination, x, y, bitmap)
Or you could use Win32Dib with its very fast drawDibToDib-routine, which
supports both a transparent color and translucency.
