If checked, this option reverse the slider in the elevation filter
so that the widget goes from high values at the bottom to low values at the top.

This option (available from the new Settings - Options - Elevation tab)
allows users to set a specific color to use as the background color
for elevation profiles. This can make the chart more readable for
certain datasets, eg point clouds with RGB coloring, where the default
background color is too close to the point colors to be discernable.
This is an opt-in setting -- by default the profiles will continue
to display using the standard system background color.
matching scales
When activated, this option ensures that the horizontal and vertical
scales are always kept equal (so that eg a 45 degree slope will appear
as a 45 degree slope in the profile)
position when drawing the marker on the map canvas to indicate the
cursor position
Otherwise things are misleading -- the elevation profile will show
snapped results yet the corresponding canvas point may be slightly
displaced from what the elevation plot is showing
Be more picky about when we force a zoom full in the elevation plot,
so that we aren't zooming out when a user makes a change like
increasing the distance tolerance or nudging the curve.
