Bug 741 HiDPI: Add ScalableSurface.getNativeSurfaceScale(..) to compute surface DPI ; Add NEWT Window.getPixelsPerMM(..) to query surface DPI
With HiDPI and surface scale, we need knowledge of the native surface's pixel-scale matching the monitor's pixel-per-millimeter value. Preserving the queried native pixel-scale and exposing it via ScalableSurface.getNativeSurfaceScale(..) to compute surface DPI. Add NEWT Window.getPixelsPerMM(..) to query surface DPI. Surface DPI is demonstrated in GraphUI's GPUUISceneGLListener0A .. and TestRulerNEWT01, etc ..
