Description

Testing

Start a new game or continue an existing one.
Open the map screen (either using the Map button or by pressing the Tab key).
Try zooming-in by scrolling the mouse wheel forwards.
Try zooming-in by clicking the Zoom In button.
Try zooming-out by scrolling the mouse wheel backwards.
Try zooming-out by clicking the Zoom Out button.
Pan the map by holding the left-mouse button on it and dragging the mouse in the desired pan direction.
Waypoints
The waypoint creation screen should be displayed when the Marker+ button is pressed and a position chosen.
The three sliders on the waypoint screen should be adjustable from 0 to 255.
The colour shown at the top of the waypoint screen should correspond to the chosen slider values.
Clicking Cancel should not place a waypoint.
Clicking Done should place a waypoint.
The placed waypoint should contain the colour chosen.
Clicking the Marker- button and then selecting a waypoint should remove that waypoint
Visual/Scale Testing
Try to view the screen on different form-factors and screen resolutions. Android builds will not see as significant a difference here because they use automatic screen scaling based on the reported display density.
Elements should not be significantly overlapping too much (a bit is alright).
Text should ideally not be wrapping mid-word.
Buttons should be large enough to be confortable to reach on Android.

This depends on #636.
This should help with #563.
The colour selection has been changed from a scale of 0-1 to 0-255, since I felt that people would be generally more familiar with the 0-255 scale.
