nano3d: remove surface-clear optimization

Browse Source 
This patch fixes a GCC-10 compile error. Even though the optimization
was quite effective - I measured a speedup of factor 2 - it is not all
that important for the overall application performance. In the nano3d
case, we are talking about 1 vs. 2 percent of CPU time.

Fixes #4140
