Daniel Gibson 565d3e3fc1 Make CstDoom3 anchored GUIs work with dhewm3's menu scale fix 
In idWindow::Redraw(), I had to make sure the menu scale fix (which,
if enabled for a window, renders that in 4:3 with empty or black bars
on the side if needed for widescreen etc, instead of stretching it)
is disabled if a window uses CST anchors, because the CST anchor code
also adjusts for the display aspect ratio and if we do both, things get
distorted in the other way.

The biggest change is that idDeviceContext::DrawStretchPic(Rotated) now
has code to adjust the coordinates for both CST and the menu scale fix,
so idDeviceContext::AdjustCoords() is mostly obsolete - it's only still
used by idRenderWindow.
Unlike DstDoom3 now that extra adjustCoords argument to those Draw
functions indicates that any coordinate adjustment should be done, so
if it's set by a caller, it's set to true.

I removed idDeviceContext::AdjustCursorCoords() because it was only used
in one place anyway
