> We are using SVG to create UI for our WeApp and we feel a need for suspendRedraw. The case is as follows. As scrolling is not supported by SVG we have implemented our own scrolling using translation but what we have observed is that scrolling is not smooth if the whole of UI has lots of images like 200 of them. Now this could be because the whole page is repainted and drawing only that  part of the svg document which has scrolling would probably solve our problem.

Would suspendredraw actually solve your usecase? If repaint is suspended, the portions of the svg document that were not visible initially would not have been drawn to begin with, and therefore would not be available when you scroll the svg portion. While drawing is suspended, the SVG portion would not be redrawn at all, which is probably not what you want.
