Cygwin/X: Make default DPI match native DPI
Make the default DPI match the current Windows DPI setting. If that
setting can't be retrieved, change the fallback DPI value from 75 dpi
to 96 dpi.
Mark the application as dpiAware in the manifest, which prevents
dpi virtualization for high (>96) dpi values on Vista and later.
