Can't force clipping in GETMAPIMAGE request (performance bottleneck in fusion)

Description
Fusion uses a GETMAPIMAGE request to render the map image. GETMAPIMAGE currently always sets the requiresClipping flag on the renderer to false. When a map contains a layer using labels, the renderer will attempt to render all the labels even when these are not inside the area being rendered. This design is intentional so that tiles rendered will have label flowing contiguously across tiles. However, when not tiling, there currently is no way to force the renderer to clip which would greatly increase performance for the this common case.
