* Put initializer values inside brackets.
* Put logical AND conditions within parentheses.
* Put assignments within conditional statements within parentheses.
* Mark unused variables as such to suppress compiler warnings.
* Fix vftable shadow warnings caused by ConVar::CreateInternal (does not implement, only interface. Renamed to yield desired behavior).
* Fix 'never' initialized class members for 'CCVarIteratorInternal'.
* Return values in interface vftables that cannot be pure virtual.
* Move render utils to dedicated file.
* Implement more render/mesh utils.
* Added structure for OverlayTriangle_t, OverlaySweptBox_t and OverlayCapsule_t.
OverlayCapsule_t has been modified to accommodate the size in r5 (2 new vectors).
