Log Message:
graphics/vv: Fix build with GCC 12 (or any other versions of GCC)

std::powf() has been standardized as of C++11, but libstdc++ from GCC still
doesn't support it. Use std::pow() instead, as it's equivalent to
std::powf() in this context.

This is really a GCC bug, not a vv bug. So I don't think we should upstream
this patch.
