[Pharo-users] Rendering text to bitmap buffer then paintImage to a canvas

I need to improve the performance of a lot of text that drawn on screen while the screen is being dragged around and would like to experiment with rendering the text to a bitmap buffer then painting that onto a canvas. How might that be achieved? And from Workspace can I test this? I have been searching for a couple of hours already so thought I'd just ask. cheers -ben
