1. Display an image
2. add a marker
3. make the marker bigger
4. move it around
5. Please notice when any edge of the indication box is out of image, the label disappears.

Fix suggestion:

Check the preference of where the indication box should be,  when that corner (plus some margin) is in the image, the label should be displayed. 

Copied from GitHub: (6/13/2018):

This development fixes the following issues,

• when the marker/footprint is moved towards the edge of the display area, the label for the marker/footprint disappears.
  fixing: showing the label when the marker/footprint is moved out of plot area and showing the label in alternate corner location in case the label is being moved out of plot area.
• when the marker/footprint is relocated farther from the center or the target of the HiPS, the footprint is shown out of shape as the image is zoomed.
  fixing: instead of translating each region component on image domain as regular image, each component is re-rendered in world coordinate per original region description.

test:
start image search
add a marker or footprint overlay
move the marker/footprint to anywhere close to the plot border and view the text display

start HiPS search (no FOV entered)
add a footprint overlay
click (relocate) at a point close to the curved border of the HiPS
zoom the image to see more detail of the footprint by zooming and rotating the HIPS
