* app/image_map.[ch]: new function image_map_clear that removes the preview without freeing the image_map. * app/brightness_contrast.c * app/color_balance.c * app/curves.c * app/hue_saturation.c * app/levels.c * app/posterize.c * app/threshold.c: Add a call to image_map_clear in the preview toggle button callback. This makes the preview toggle button behave as expected. * app/histogram_tool: remove an unnecessary include.
