Support specific XCURSORPATH or search XDG_DATA_DIRS
Currently there is no method to change the hardcode XCURSORPATH.
However, when using with some complex systems(such as flatpak/snap/nix), it may be needed.
We should support XDG_DATA_DIRS which is described in XDG Base Directory Specification, or at least supports specific XCURSORPATH when compiling.
To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
