Research direction

Start by comparing ofCairoRenderer's frame handling with the OpenGL renderer, focusing on how ofTranslate state is carried into a new frame. Reproduce the issue with ofTranslate without ofPushMatrix/ofPopMatrix, then verify that the Cairo renderer resets translation between frames while preserving the existing matrix-stack behavior.
