Suspicious `xor-used-as-pow` warnings
Either the warnings are correct and there is a bug, or the warnings are wrong and the code is written in a really stupid way:
../../modules/visualization/glspectrum.c:528:43: warning: result of ‘2^16’ is 18; did you mean ‘1 << 16’ (65536)? [-Wxor-used-as-pow]
../../modules/visualization/visual/effects.c:216:40: warning: result of ‘2^16’ is 18; did you mean ‘1 << 16’ (65536)? [-Wxor-used-as-pow]
