Window size discrepancy on HighDPI monitor

Running the same sketch on a HighDPI monitor appears to create a larger window than necessary.

Inizia con la chiamata size(640, 360) nello sketch fornito e confronta la creazione della finestra e il comportamento HighDPI sui due tipi di monitor. Segui il punto di ingresso per il dimensionamento della finestra nell'implementazione; il lavoro è completato quando lo stesso sketch produce la dimensione della finestra prevista e coerente sui display HighDPI e standard.
