Colorstops show black color (ie invalid color) at 100% of segarc range

[AmoebeLabs]

Bug description

Sometimes the colorstops shows a black color at the end of the range although the colorstop value is larger then the maximum value.

The following colorstop should work for a value of 60: it should show orange, but shows black in the segmentedarc. It should even work with an end value of 55: that color should be used for any value larger than 55...

Screenshots are from example view-sake10.yml

But it doesn't work for some reason

Still going strong just above 55 degrees:

(Optional): Suggested Solution

It seems that the setting lastcolor is the culprit: it doesn't calculate the segment/entry in the colorstop in the correct way...

[AmoebeLabs]

The problem is that the colorstop must match the min/max scale.

In this case the last entry is 65:, and the max scale is 60. So the 65 is ignored!

Another fix is that if the last entry is 55, the software now checks if a colorstop is defined for the max scale value, and if not, it just adds the last color in the list again at that value to make sure there is a value for the max scale value.
