Getting to the bottom (or top?) of texture and FBO orientation


#1

In OpenGL, textures are drawn with 0,0 at the bottom left, which often calls for an adjustment before drawing to fbo or screen.

How does Cinder handle texture and fbo alignment? Where is the (0,0) point in each? How does Cinder 0.8 vs Cinder 0.9 handle this?

Does Cinder make other compensations, for example when shaders are applied?

I’ve been trying to follow different discussions of this in the forum, but I can’t find my way to a concise summary.
