Flushing the clip state no longer does anything that would cause the journal to flush. The clip state is only flushed when flushing the framebuffer state and in all cases this ends up flushing the journal in one way or another anyway. Avoiding flushing the journal will make it easier to log the clip state in the journal. Previously when trying to set up a rectangle clip that can't be scissored or when using a path clip the code would use cogl_rectangle as part of the process to fill the stencil buffer. This is now changed to use a new internal _cogl_rectangle_immediate function which directly uses the vertex array API to draw a triangle strip without affecting the journal. This should be just as efficient as the previous journalled code because these places would end up flushing the journal immediately before and after submitting the single rectangle anyway and flushing the journal always creates a new vbo so it would effectively do the same thing. Similarly there is also a new internal _cogl_clear function that does not flush the journal.
