Drawing and clipping to paths is generally quite expensive because the geometry has to be tessellated into triangles in a single VBO which breaks up the journal batching. If we can detect when the path contains just a single rectangle then we can instead divert to calling cogl_rectangle which will take advantage of the journal, or by pushing a rectangle clip which usually ends up just using the scissor. This patch adds a boolean to each path to mark when it is a rectangle. It gets cleared whenever a node is added or gets set to TRUE whenever cogl2_path_rectangle is called. This doesn't try to catch cases where a rectangle is composed by cogl_path_line_to and cogl_path_move_to commands. |
