/* zoom: functions to transform from image space to unrotated display

*/
Bug 791741 - Transparent rectangles when image is drawn Add gimp_display_shell_[un]transform_with_scale(), which are similar to gimp_display_shell_[un]transform(), however, they transform the bounding box to/from uniformly-scaled image space, given the scale factor as a parameter. These functions are more accurate than using gimp_display_shell_[un]transform() and applying the scaling separately, in particular, when the scale matches the (horizontal or vertical) display scale. Use these functions in gimp_display_shell_draw_image(), to avoid an off-by-one error when transforming screen-space chunks to image- space chunks, which leads to the symptoms described in the bug. Fix another potential off-by-one error affecting non-uniformly scaled images, and window scale factors other than 1.
