Polish tiling view

• 1. markers are broken, the vertical location have to be synchronized
• 3. the screen is really wide, it would be good to center to toolbar
• 6. the colormap lut/norm/limit is not stored/restored
• 7. colormap params which will not be often changed have to be merged together
• 9. it would be good to center the label together with the state
• 12. readability of the camera could be improved
• 13. the marker color selection could be moved together with the mode (using a permanent drop panel)
• 14. plot axis could use the real motor names
• 2. would be good to use a grab to zoom with the mouse, cause the region is really big (and for consistency with silx anyway)
• 4. changing the size of the window reset the view, it would be good to not change the zoom at all and restore the center of the previous view to the new center of the view (for each plots)
• 5. there is missing reset zoom -> on screen, on tiled object, on the camera
• 8. it would be good to add the tiling scans here
• 10. would be good to not trig the screen with middle/right mouse buttons (if there is nothing special with them)
• 11. no display of the actual sample name
