Draw spell icons inline and make scroll speed framerate-independent

Browse Source 
Prefix the icon as a ClassicAPI |T escape instead of a separate texture
region, so it fades and scales with its text and counts toward alignment.
Scale the scroll step by elapsed time so text moves at the same speed at
any framerate.
