5 // Demo of text annotation with gravity. Produces an animation showing
6 // the effect of rotated text assize_t with various gravity specifications.
7 //
8 // After running demo program, run 'animate gravity_out.miff' if you
9 // are using X-Windows to see an animated result.
10 //
11 // Concept and algorithms lifted from PerlMagick demo script written
12 // by John Christy.
