Revision ec231614

Added by Leszek Koltunski about 7 years ago

Major refactoring: convert the Matrix Effects to be independent of the resolution of the surface we render to.

Re-write the first 15 apps to work with this.

644 
 *               the vector's unit is the size of the surface in each direction; i.e. a move(0.3,0.7,0.0)
645 
 *               will move our object 30% of the width of the surface to the right and 70% of its height
646 
 *               down.
