iabdalkader b46ba79557 Update JPEG frame buffer after loading/creating images.
* With this fix the frame buffer will be updated instantly after loading or creating
new images with the copy_to_fb flag set to true.
* There's no need to flush the framebuffer after loading or creating images anymore,
however the sensor (or image) flush() still needs to be called after drawing to see the updates.
