Alexander Gavrilov 4d3bfb3f41 Subdivision Surface: fix a serious performance hit when mixing CPU & GPU. ... Subdivision surface efficiency relies on caching pre-computed topology data for evaluation between frames. However, while eed45d2a23 introduced a second GPU subdiv evaluator type, it still only kept one slot for caching this runtime data per mesh. The result is that if the mesh is also needed on CPU, for instance due to a modifier on a different object (e.g. shrinkwrap), the two evaluators are used at the same time and fight over the single slot. This causes the topology data to be discarded and recomputed twice per frame. Since avoiding duplicate evaluation is a complex task, this fix simply adds a second separate cache slot for the GPU data, so that the cost is simply running subdivision twice, not recomputing topology twice. To help diagnostics, I also add a message to show when GPU evaluation is actually used to the modifier panel. Two frame counters are used to suppress flicker in the UI panel.
