[PATCH 0/3] MR6846: winex11: Misc tweaks to the emulated display mode support.

[Rémi Bernon (＠rbernon)]

This fixes window size being broken when dragged over multiple monitors with different scales and adds support for padded fullscreen windows when physical display mode aspect ratio doesn't match the emulated one.

[PATCH 1/3] winex11: Allow updating the window size during a ConfigureNotify event.

[Rémi Bernon]

From: Rémi Bernon

Fixes broken window sizes when dragging over to a monitor with a
different DPI.
