Description
When trying to draw a texture in a Fbo, setAnchorPercent() doesn't have the desired effect. setAnchorPoint(), however, works as expected
// draw texture into fbo
fbo.begin();
ofClear(255, 0);
ofPushMatrix();
ofTranslate(fbo.getWidth()/2, fbo.getHeight()/2);
tex.setAnchorPoint(0.5, 0.5);
// tex.setAnchorPoint(tex.getWidth()/2, tex.getHeight()/2);
ofSetColor(255);
tex.draw(0, 0);
ofPopMatrix();
fbo.end();

Research direction
Reproduce the issue using the shown Fbo drawing example and compare ofTexture's setAnchorPercent() behavior with setAnchorPoint(). Trace the implementations and call path for those anchor methods, then verify that percentage-based anchoring matches point-based anchoring when the texture is drawn into an Fbo.
