improve loading performance of large textures:

Browse Source 
option to disable tinyrenderer, use p.configureDebugVisualizer(p.COV_ENABLE_TINY_RENDERER,0)
also make sure to use p.configureDebugVisualizer(p.COV_ENABLE_RENDERING,0) before loadURDF, and enable rendering afterwards using p.configureDebugVisualizer(p.COV_ENABLE_RENDERING,1)
reorder 2 loops, making the flip texels twice as fast (cache coherency),
single memcpy of entire texture in tinyrenderer, instead of per-pixel copy (memory layout is the same)
add lots of B3_PROFILE timings, to see where time is going
