Fix hittest not working correctly on non client mouse messages on high DPI Windows.
Fix hittest not working correctly on non client mouse messages on high DPI Windows.

This caused minimize/restore/maximize buttons to be non functional in the opaque browser frame on
high DPI Windows.

The non client mouse messages have the coordinates in screen in pixels. When we convert the native mouse
event to our Event object we convert from pixel to DIP. When the event is dispatched it is transformed to DIP
again which causes this issue.

Fix is to not convert from pixel to DIP when the non client mouse message is converted to the Event object.
This is on same lines as regular mouse messages.
