linux: no longer opens under wayland

[corvid3]

Main_OpenWindow:main.cc has some x11 specific code; specifically it seems the lines that set up the window icon at around line 690 causes a segfault if not using x11 (i.e. fl_display == nullptr).
i've edited those lines to not run when fl_display is null, and it starts right up. works as well as ever.

Hmm, odd, what system are you using? I'm on Ubuntu 24.04 LTS with Wayland.

Could it be that you need to install X11 components to be able to run it? I'll try at least to make that part of the code safe.

i'm running a relatively recently updated gentoo (6.6.38) w/ sway. i have both the wayland & X11 ecosystems installed. using i3 (x11), eureka launches w/ my bodge patch removed. i'll check some USE flags & run another system upgrade and see if that changes anything.
