Need non-AWT ways to get display count, width, height, pixel density

Created by: benfry

We need either 1) an alternative/native method to make these work, or 2) a per-Surface version of them.

The second option is still problematic since we don't know what PSurface will be used when settings() is called. So either we need to start passing that to the command line, or do something more clever, i.e. once size() or fullScreen() is called, use the renderer to create an object that can handle these device settings on a per-surface type basis.

For now, displayWidth and displayHeight will be 0 when --disable-awt is used.

まず、--disable-awt を使用したときに displayWidth、displayHeight、ピクセル密度がどのように扱われるかを追跡し、次に issue で言及されている size()、fullScreen()、renderer、PSurface のパスを調べます。完了の条件は、ディスプレイの寸法に対して 0 を返すのではなく、定義済みの非 AWT 実装または実用的な Per-Surface アプローチを提供することです。
