Does GDI+ have the ability to retain a sub-coordinate system? For example,
say I create a triangle spaceship through a graphics path with the ship
pointing in the direction of the x-axis. Then I rotate that ship slightly.
Then I want to translate the ship forward (no longer parallel to the
x-axis). Do I have to manually calculate the translation or does GDI+
provide a sub-coordinate system so that I can just add 1 unit of distance to
the spaceship's x coordinate.

Thanks!
Chris

You have to calculate the position yourself.
