Based on a patch by Massimo. Move the entire image-space/screen-space transformation logic from gimp_display_shell_render() to gimp_display_shell_draw_image(), so that the former works entirely in image space, and do the chunking and clipping in screen-space, making sure that image-space chunks are never larger than GIMP_DISPLAY_RENDER_BUF_WIDTH x GIMP_DISPLAY_RENDER_BUF_HEIGHT, even when the window's scale factor is greater than 1. Add a GIMP_BRICK_WALL environment variable, which, when set, shows the screen-space chunk bounds.
