### Problem description
Because of `s_drawTexture` never being set to true, textures rarely or
never drew in the 3D visualizer.
### Implementation description
Set `s_drawTexture` to true when correct (valid texture file/object).
### Problem description
The fonts list on Linux does not show all system fonts, and does not
show font names at all.
### Implementation description
Use Fontconfig to make the list less bad if Fontconfig headers are
available.
### Additional things
I like fonts.

### Problem description
ImHex asks users whether they wish to opt-in to network connections on
start (excellent!), then ignores that and tries to connect to the
network anyway when the welcome screen loads (less excellent!).
### Implementation description
Also don’t connect to the network on the welcome screen if it is
supposed to not do that.
### Problem description
WerWolv/ImHex#1814
### Implementation description
1. Remove the flag that wrongly tells `ImFontAtlas` that it owns font
data, and remove that parameter from the function signature entirely
since now it is always `false`.
2. Rename `takeAtlas` to `getAtlas` since it no longer transfers
ownership as of b652565b57.
This PR updates the nativefiledialog submodule and uses its new feature
to set the ImHex main window as the parent of the dialog window. This
ensures that the dialog stays on top of the main window. This is
currently supported by NFDe on Windows, macOS, and Linux/X11.
Linux/Wayland behaves as it did previously due to limitations in NFDe.
Note that macOS file dialogs have already been parented properly as NFDe
previously used the key window (the window currently receiving keyboard
events) on macOS. However, it's probably better to do the correct thing
and pass the main window to NFDe even on macOS.
### Problem description
The file dialog go behind the main window if the main window is clicked
while the file dialog is open.
### Implementation description
Update nativefiledialog and pass the `GLFWwindow*` of the main window to
the library function.

### Additional things
I have tested this on Windows and Linux/X11, but did not test this on
macOS. It would be ideal if someone can help with this. (But as far as
NFDe is concerned, macOS `NSWindow*` handles have been tested (with
SDL2) and works.)
