I want to use a custom bush for my calligraphy programme. It's no problem to paint with this brush. I just use BitBlt while the mouse button is pressed.
But when I move the mouse a little more faster I won't get a line of course. It's also no problem to remember the last point and draw a line between the last and the current point but that makes no sense when using a custom brush.

Is there any possiblity to solve this problem? I'm feeling so bad when I look at the calligraphy brush in Adobe Illustrator because this is excactly what I want. How do they do that?
