Re: EDGE_FULL_BACKGROUND

I did some poking and the left-right problem isn't a local problem on my 
system. It's a fundamental bug of Gtk based/built Scintilla.

https://community.frame.work/t/responded-fedora-39-40-beta-gnome-45-46-dual-monitor-window-positioning-issue/47841

When initially hooked up to my NVS 510 card these monitors are "found" 
in the wrong order.

Like everybody else I drug them around and saved.

People who run even more monitors

4-monitor setup

Have even more issues with Gtk based applications. It appears Gtk gets 
the monitor information from the hardware or OS level, not the desktop 
level so it is completely unaware of position and orientation changes 
made by the user. As such, rectangle math cannot be trusted. It is also 
why the first cut using FillRectangleAligned() filled in the wrong 
direction.

Just passing along since this won't be an issue in CsScintilla

Qt has its own multiple monitor bugs

>>     It's all too complex. There appears to be some local problem with the order of left and right on your platform. There's also some unnecessary casting/truncation. It can just use the right side of the requested drawing rectangle and rely on FillRectangleAligned so there isn't a fuzzy partial pixel edge.
