The `target` Event property is readonly as it is set internally when an
event is dispatched. This change uses a plain object with the essential
properties that a PointerEvent has which is sufficent for map event handling
Pass the view projection to the geometry function so circles and other custom geometry can be given the expected shape/size in the view while being defined in user coordinates.
Add tests to draw circles in a user projection and along both axes
Draw regular polygon in a user projection
Draw box in a user projection
API changes:
* (breaking) the `rotate` method is gone
* the `adjustRotation`, `adjustResolution` and `adjustZoom` methods are now
available and allow using an anchor.
This means interactions do not have to do the anchor computation themselves
and this also fix anchor computation when constraints must be applied.
This commit aims to simplify the computation of zoom and resolution in the
View class.
Previously zoom levels and resolution computations were mixed in different places,
ie resolution constraints, initial values, etc.
Now the View class only has the `getZoomForResolution` and `getResolutionForZoom`
methods to convert from one system to another.
Other than that, most computations use the resolution system internally.
The `constrainResolution` method also does not exist anymore, and is replaced
by `getValidResolution` and `getValidZoomLevel` public methods.
This introduces a breaking change:
The `extent` view option now constrains the whole viewport and not just the
view center.
The option `constrainOnlyCenter` was added to keep the previous behaviour.
Constraining the whole viewport and not only the view center means
that the center and resolution constraints must be applied with a knowledge of
the viewport size.
Instead, only prevent default on handled pointerdown events. This makes
the `focus` condition work with interactions that involve dragging on
touch devices.
