annotate engine/core/view/renderers/blockinginforenderer.cpp @ 407:f27880d4c08c

Moved getAngleBetween() form Camera to angles.h and updated it to not use the camera angle in it's calculation. Added camera rotation to the angle calculation for selecting the correct image by angles. Added a call to setRotation() to make sure that instance rotation is valid.
