Thanks. Knocking off few points off my intelligence test for having to be told about triangles.
As you seem to be in the know, any off the cuff suggestions for how to render text off the viewport to match text size to a box by iterating font sizes, one which may recommended in the case of pyglet? e.g. drawing to coordinates off the scale v.s. using some invisible canvas or window? anything that would be less likely to break between pyglet revisions or be a more stable way to draw invisibly every now and then for size matching fonts to shapes?
