I basically hadn't touched the X11 version since the Twentieth Century, so it was looking pretty threadbare compared to other platforms. I replaced the 1991-vintage Xlib version with a backport of the macOS OpenGL version to GTK 3. Let me know how it works on your incomprehensibly powerful hundred dollar supercomputer.

Source only release. I didn't bother re-spinning the various other platform builds just to bump the version number.

Previously, previously, previously, previously, previously, previously.
