Subject: Define CompareResolution call operator as const
Because this custom comparator is used as constant reference in the
std::set implementation, its methods cannot change its internal state.
Declare that the function call operator doesn't do that, and therefore
can be called whenever we have a constant reference.
This resolves an issue when building with GCC 15, where no matching
method would be found:
/usr/include/c++/15/bits/stl_tree.h:2604:36: error: no match for call to
‘(const MOGL_Fenetre::CompareResolution) (const
MOGL_Fenetre::MOGL_Resolution&, const MOGL_Fenetre ::MOGL_Resolution&)’
MOGL_Fenetre.h:55:14: note: passing ‘const
MOGL_Fenetre::CompareResolution*’ as ‘this’ argument discards qualifiers
