Revert "meta: Remove rofi"

Some programs expect rofi to be installed. Although dmenu is nice, rofi
is more customizable and has the potential to look nicer overall.

+# This script will find the X server DPI and apply the necessary
+# settings to make Rofi, X, GNOME, and KDE applications have the
+# proper scaling, with no intervention from the user necessary.
+
+# Note that XDG_CURRENT_DESKTOP is required for KDE/Qt applications to
+# have the proper theming in non-Plasma environments. In contrast, GNOME
+# respects its theming even when XDG_CURRENT_DESKTOP is not set to it
+# (through settings.ini).
+
+# Note that the xcursor size is specified with:
+#
+#   1. The X server resource database (xrdb), of which cursor size is
+#      only applied BEFORE your window manager starts
+#   2. The xsetroot command, which affects the cursor shown on the root
+#      window (your desktop)
+#   3. The XCURSOR_SIZE environment variable, which affects the current
+#      program
+#
+# There are a few things to take away from this:
+#
+#   1. The root window (desktop) cursor size MUST be changed with xsetroot
+#   2. KDE applications will honor XCURSOR_SIZE but NOT xsetroot
+#   3. GTK applications will honor xsetroot but NOT XCURSOR_SIZE
+#
+# Additionally,
+#
+#   4. SOME X applications require XCURSOR_SIZE to be set and will NOT
+#      honor xsetroot
+#   5. SOME X applications require xsetroot to be set and will NOT
+#      honor XCURSOR_SIZE
+#
+# So for a consistent variable cursor DPI environment, one has to set BOTH
+# xsetroot and XCURSOR_SIZE
+#
+# Note that existing windows will NOT have their X cursor size changed
+# if they don't depend on xsetroot. Because of this, and because of the
+# fact that active windows will not handle DPI changes anyway, you should
+# probably have no GUIs running when switching DPI.

+# rofi
+
+[rofi][rofi] is an application launcher, window switcher, and dmenu replacement.
+
+## Use Cases
+
+rofi can be used to:
+
+- Launch applications based on `.desktop` files
+- Show all open windows and switch between them
+- Parse dmenu-like input
+
+You should not use rofi if:
+
+- Your desktop environment already has an application launcher and window switcher
