I'm not sure 100% that this PR introduces a breaking change in the projects that uses this. There could be some problem related to the fix made in drawsupport when a polygon is drawn because in ol it was missing the last vertix

Other information:
For testing this try to draw a spatial filter and then activate the sync. the features should be filtered based on the drawn spatial filter.

Just discovered a problem related to the fact that nativeCrs definition for proj4 could be missing and this leads to some error we need to handle as first thing.
we can consider other solutions (fetch dinamically the proj definition) but I need help with this.
@mbarto @offtherailz @tdipisa opinions?
