* Make Windows DPI aware to display properly on high-resolution screens. * remove empty line * Don't use app manifest, set process dpi aware programatically. Store variables in Program.cs for use instead of re-creating them per class/ method. * Fix for linux/osx * Add braces * Re-use manifest. It appears to be required on linux. * Undo previous commit -- it appears linux was simply never affected. * Addressed AcK's comments * Remove unused usings * Address comments by AcK #2 * Re-order * Move FromHwnd call to ForceDpiAware class. Wrap in Try-Catch to prevent crashes on systems that don't support it. * Additional code cleanup * Remove "global::" reference.
