Coming just a month since the last release, you won't be surprised that this version is somewhat small overall.  It includes some more fixes that I thought about releasing as 3.37.3.  However there is also a broad variety of quality of life improvements that this release deserves a .0 update.

In the Geom Browser, the Show Only, Show, and NoShow buttons now work like the other things (like Hidden, Shade, Feature lines) with respect to applying changes recursively.  I.e. now they only recurse a collapsed tree.  When you Show or NoShow a parent entity on an expanded tree, the visibility change only affects the selected entities.

The number of Sets is now user-adjustable.  Go to the Set Editor, click the arrows at the top of the window.

Measure (probe, ruler, protractor) now works for non-surface Geoms.  This is mostly for blank and hinge geoms, but works in a rudimentary way for Mesh and HumanGeom (it always measures from their component origin).  So users who use Blanks extensively as intermediate coordinate systems can now use them for all their Measure needs.

Several improvements around advanced links.  Unique variable names are now enforced when renaming variables.  The variable renaming buttons were re-worded for clarity.  Multi-line error messages are now displayed when links break.

The full-path filename at the bottom of the screen is now displayed in a larger font for better visibility on high resolution screens.  The filename (without a path) is now displayed in the title bar at the top of the screen.

The integrated flowpath engine extension has a pair of improvements.  First, streamtubes are now extended to a constant X value -- even when the start of the streamtube is not at a constant X.  There is also a new option to auto-determine the extension distance based on the overall dimensions of a selected Set.

Height/width/area/aspect sliders are now displayed for CEdit type XSec curves -- even when the detailed editing window is not displayed.  This should allow for quick adjustments without having to get deep every time.

Better patch names are assigned to wing patches when exporting STEP and IGES files (Thanks Jeff V.).  This should make it easier to identify wing trailing edge, upper, and lower surfaces in meshing tools.

There is also now an option to merge the lower and upper trailing edge patches together (and leading edge too).  Some meshing tools did not appreciate that we output split TE patches -- so now we'll merge them.

As usual, there are a few bugfixes too -- mostly related to graphics glitches that were introduced in 3.37.0.

I don't think there are any high risk changes in this -- and hopefully the graphics glitches introduced in 3.37.0 are calming down.  Everyone should update.

Thanks for this. Unfortunately the bugs I reported for Ubuntu 22.04 are still there (tiny text in menus and almost unusably slow update when moving sliders).
