Taking the 'zoom factor' in account when moving a vertex with the arrow keys.
Making sure the video is not tinted.
Fixed the video auto play.
Can only delete a vertex if the shape is a 'mask' with more than 3 vertices.
Added a get method that return the number of vertices.
Housekeeping.
Clearly showing that we need to use GLFW.
Updated the edit Zoom and Drag functionality. Needs some more tests, cleaning and refactoring still.
Compiling with OF 0.8.3 [ofxExtraWindow]
