// TODO(Ed): Change this to be whitespace aware so that we can optimize the caching of shpaes properly.
// Right now the entire text provided to this call is considered a "shape" this is really bad as basically it invalidates caching for large chunks of text
// Instead we should be aware of whitespace tokens and the chunks between them (the whitespace lexer could be abused for this).
// From there we should maek a 'draw text shape' that breaks up the batch text draws for each of the shapes.
