We should be able to differentiate between OpenGL render (viewport render), offline render (F12), and view render (viewport draw). This allows for us preventing offline render to skip mode drawings, grid, ... Even OpenGL render can benefit from this forcing a higher quality anti-alias and sampling than the viewport drawing. I'm not sure if it's clever to keep the memset(0x00) outside the render loop function as it is in this patch. An alternative is to just pass the render "type" as a flag to the render function, and set DST.options inside it. (I may change this tomorrow, I will wait to hear from Campbell on that).
