Description
getting some strange results when using ofDrawBitmapString on ofGLProgrammableRenderer.
ofDrawBitmapString("testing", 20, 20); - should just draw a white bitmap string.
instead it draws it on a background and the text is yellow.
this is how text labels are rendering using ofxUI.
and i think this might be using a ofTrueTypeFont for the labels.

Research direction
Start by reproducing the issue with ofDrawBitmapString("testing", 20, 20) on ofGLProgrammableRenderer and compare the result with the expected white text. Then inspect the bitmap-string rendering path and the ofxUI text-label behavior; done means the text renders without the unexpected background and yellow coloring.
