When using a MatrixTransformationFrameProcessor per transformation matrix, each frame processor's shader applies the matrix to the vertices and clips the result to the NDC range when drawing the output frame. This change combines consecutive MatrixTransformations into a single MatrixTransformationFrameProcessor by multiplying the individual matrices while updating and clipping the visible polygon after each matrix and mapping the resulting visible polygon back to the input space so that its vertices and the combined transformation matrix can be used in the shader.
