After setting the view and projection matrices, no text renders.

Two bug have been figured out

text glyph advancement is done in the projection space. The text renderer does not know the users chosen space, the advancement needs to be passed to the shader for projection space processing.
in the shader, the position is not correctly transformed by the matrices

The transformation issue seems fixed but the scaling of the text for different viewport sizes is now broken.

the view regions aspect ratio need to be considered. Maybe taking it out of the projection matrix might work.
