Inconsistent mouse camera controls

[maxsupermanhd]

In huge square map when panning camera both X and Y axis are panning with same speed but that's not the case on very narrow but long map.

Note: faulty line is here, should be replaced with a configurable constant https://github.com/Warzone2100/warzone2100/blob/c8e597da4ec72fead9fe00edf5b03f1b12d23e29/src/display.cpp#L1210

How about change like this?

1. We can calculate the coefficients by dividing the short axis for the long axis on the map.
2. It is corrected by multiplying the coefficient by the panning speed corresponding to the long axis. ex) if (mapWidth > mapHeight) { horizontalMovement = panXTracker->setTargetDelta(coef mouseDeltaX panningSpeed)->update()->getCurrentDelta(); verticalMovement = -1 panZTracker->setTargetDelta(mouseDeltaY panningSpeed)->update()->getCurrentDelta(); } else { horizontalMovement = panXTracker->setTargetDelta(mouseDeltaX panningSpeed)->update()->getCurrentDelta(); verticalMovement = -1 panZTracker->setTargetDelta(coef mouseDeltaY panningSpeed)->update()->getCurrentDelta(); }
