Defined in:
lib/ruby2d/camera/text.rb

Overview

Wraps existing variables as well as adding new methods so that it can be handled by the Camera Module TODO: note that text could not be resized at the current iteration of Ruby2D so the math needs to be changed compensate for this. When Ruby2D gets updated to allow text resizing the math will need to be corrected again(see image_wrapper.rb for reference, that has math that allows for resizing)
