now using ofPushView() and ofPopView() to save and restore the model view projection matrix.
fixed a small bug where drawMarkerRect() was always drawing only the first marker in the stack.
added setMaxNumOfMarkers method.
replaced all gl calls with OF gl wrapper functions, so in the future it works with ES2
removed translate and scale from begin/end methods.
using glMatrixMode() instead of ofSetMatrixMode()
as its not yet available on develop branch but will be when merged with ES2 changes.
removed duplication of code.
fixed a small bug with incorrect index in for loop.
missed simulator guards in one of the functions.
its now possible to get the angle of a marker (around y-axis) to the camera.
good for facing 3d models to the camera.
added bUpdateCameraPixels flag to update camera pixels only when requested.
by default this value is set to false.
