The current cursor configuration poorly accomodate applications not
following the XDG icon theme spec. As a result, some applications fail
to locate user defined icons and themes.
To address this, symlinks from icon directories in the provided cursor
package was to $HOME/.icons were added added for greater compatibility
with applications using hardcoded icons directories. This approach was
chosen to allow for coexistence of declarative and non-declarative
icon files in the icons directory. In addition, symlinks of icon
directories were mirrored in $XDG_DATA_HOME/.icons for backwards
compatibility. As per the XDG icon theme spec, applications are to
search in $HOME/.icons first for icons and themes so the existing
behavior should not break for XDG compliant applications[1].
