Graphic Effectus - Rotate Text

[Malkey]

Still looking at GDI+ functions.

This one rotates text on the desktop.

Press Ctrl key - alternates between the two examples.

Press Esc key to exit.

The graphics can be dragged.

Once again, nice work! This is a very good example for people to learn from.

Any updates on this function ?

Won't compile on current autoit version
