OPM BaseMaps origin of coordinates

[All4Gis]

Hi

Just for reporting.

I'm looking at the basemaps examples and the openlayers examples are not correct using.

With leaflet this can be fixed with the tms parameter or using {-y}. Leaflet documentation, but OL doesn't have that option (or I can't find it)

For this reason the examples on this website, https://www.openplanetary.org/opm-basemaps/shaded-colour-mola-elevation, would not be correct.

We can use {-y} and in both libraries (leaflet >= 1.0) to solve this error. The same applies to the wiki https://www.openplanetary.org/opm-basemaps/shaded-colour-mola-elevation, the required TMS option is only available in leaflet <= 0.7.
The recommended way for both libraries is use {-y} instead {y}
I haven't tried them all, but they all look wrong.

I just wanted to inform you about this, Great job!
