Provides all of the normal text widget functionality, along with a text annotation type of 'block' (aka textblocks), which allow geometry management over the text within the rows of the block. Allows one to do things like fractions, radicals, labeled equations, editable buttons, etc. Also supports arbitrary lines drawn within its text box. Doc on the new text widget can be found at Version 1.6.3 now available.
