Returns whether the spell currently awaiting a target requires a glyph slot to be chosen.
Only applies when the player has attempted to cast a spell -- in this case, the "spell" cast when one uses a glyph item -- but the spell requires a target before it can begin casting (i.e. the glowing hand cursor is showing).
See also Spell functions, Glyph functions.
