fix vertical monitor transitions & 'failed to load cache' errors

[Nynxz]

Fixed Issues:

• Transitions on vertical monitor's were having issues
• [WARN] failed to load cache: there is already another swww process running errors on wallpaper changes

Discussion: Wallpaper changing animations do not work on vertical monitor

have not written rust,
I am not sure if this causes issues with 56928f7

I believe the problem with this is that it wouldn't reload the image if the output's configuration changed. That was the original reason for that commit.

I also do not understand how this could possibly be the solution to #386. There seems to be a more fundamental issue we have to address.

Not sure, the issue did not exist before 56928f7
I feel it would be better to remove the problem code and try fix what was intended by 56928f7 (refreshing when monitor input changes) a different way
over trying to fix the issue 56928f7 caused. I.e listening to actual wayland events, rather than constantly polling for whether the 'surface has changed', which is what it seems like its doing currently, and causing a memory leak.

there is also a memory leak if transitions get overwritten midway through (changing the wallpaper too quickly)
but that is a separate issue to these ones.

It seems to be working now (after upgrading to Hyprland 47), so I closed the original. Unfortunately so many things broke in hyprland 47 for me that I will be switching back to 46 for now, meaning I have to live with the animations.

Alright, we may have the proper fix for this in PR #439, actually.
