* Ensure zoom is within span when adding a layer with min/maxzoom, fixes#4915.
* Add tests written by @theashyster
* Add tests to verify map's zoom is actually adjusted to layer's min/max
`addData`, `resetStyle` and `setStyle` methods of `L.GeoJSON` actually return `this` (the current GeoJSON Layer Group), not any Layer.
Can be especially confusing in the case of `resetStyle`, where we pass a layer as argument, and with `addData`, which can accept a single GeoJSON feature, hence we could (mistakenly) think that it returns the newly created layer.
detailed that modifying `L.Icon.Default.prototype.options` only customizes the icon, but it remains an image-based icon.
Added a paragraph about completely replacing the default icon, so that it can now be anything (including a divIcon).
as proposed in a recent issue.
This change should not affect the code, it is only for consistency with docstrings.
docstrings: replaced southWest and northEast argument names by corner1 and corner2, to try to prevent confusion that Leaflet will keep these corners at those places, whereas it actually "re-orders" them to keep lowest values West-most / South-most, as if they were just corners.
Also, fire mouseover for at most one layer for every mousemove,
preventing overlapping features from firing multiple
mouseover/mouseout (#4495).
Close#5028. Close#4495.
Bug when using map option `preferCanvas: true` (canvas renderer for paths) and removing then adding back a vector within the same animation frame (typically in the same sequence, as done by Leaflet.markercluster at `"zoomend"` event, to remove layers and clusters outside visible bounds).
This commit clears the `_removed` flag from paths when they are added to the canvas.
Also added corresponding test suites.
1. Improve some of the language to be more readable
2. Correct reference to night style base map, which isn't actually used
3. Add detail that it's possible to style the text in the control
* Fix doc: add clarification for projection; closes#4817
Adds clarification in the documentation that specifies that the
`project` and `unproject` methods cannot take in arrays, but only
actual instances of `L.LatLng` and `L.Point`, respectively.
* Fix doc: add clarification for transform methods
Changes the word "real" for the word "actual" so that people don't
confuse actual instances of `L.Point` with coordinates using real
numbers.
