Transforms Global placement and color transformations
The old name for this class is Screen, which was changed in 1.8 for compability reasons. You can still use the old name by defining OL_USE_SCREEN_ALIAS before including OpenLayer.hpp. Note that the position transformations, color channels and clipping only apply to the objects which are rendered after the transformation is set. The tint color, on the other hand, will take effect during the next call to Canvas::Canvas/Refresh.html">Refresh. As usual, all positions are in pixels and angles in radians. For advanced users: Note that the original transformation state is stored in the matrix stack. Member functions
