the statement within th IF does not make any sense for my poor
understanding. As I read the code, the first IF could also be
totally removed, since as soon as exiting the first IF, all value
are lost.
Looks like a leftover from the previous version where nWidth was
calculated only locally without the result ever being assigned to
mnWidth and the local nWidth being returned. With the change that logic
changed, the mnWidth member variable still not being assigned a value
but returning mnWidth. I guess the correct approach would be to remove
the local long declaration so that it reads
if( !mnWidth )
{
mnWidth = mnBaseAdv;
for( int i = 0; i < mnGlyphCount; ++i )
mnWidth += mpGlyphAdvances[ i ];
}
