[Feature request] Additional controls to interactively change overly offset and size

[laheller]

Hi @EricClaeys !

As the documentation about constellation overlay says, it is very hard & time consuming to properly align the constellation overlay with the real star map coming from the camera. It's kind of annoying to play with the configuration.json entries and then refresh the website to check the results. The idea is to add some additional controls, like buttons for example to a new bottom panel which appears only when the constellations overlay is enabled. The following buttons could be connected to and change the value of settings interactively:

• a pair of buttons with label Size - and Size + to decrease/increase the overlay size (while keeping the aspect ratio) => overlayWidth & overlayHeight in the configuration.json
• a pair of buttons with label Offset X- and Offset X+ to change the horizontal offset of the overlay => overlayOffsetLeft in the configuration.json
• a pair of buttons with label Offset Y- and Offset Y+ to change the vertical offset of the overlay => overlayOffsetTop in the configuration.json

@laheller, thanks for the suggestion. I added your idea to the existing enhancement request for improving how the constellation overlay is changed. So, I'm closing this Issue. Please post any follow-up to the other Issue.
