[PATCH 0/1] MR10823: winex11: Allow user to set WM_CLASS

[Nicholas Little (＠njlittle)]

This commit allows the user to optionally set the WM_CLASS by setting an
environment variable WINEWMCLASS with the aim of allowing him to ensure
desktop environments can correctly identify wine windows, unfortunately
the executable filename isn't always sufficient as some programs share a
common executable name.
