hover-setTimeout makes hover feel very laggy

[moritzschaefer]

        } else {
            hoverTimeout = setTimeout(function () {
                var hit = featureLookup(rx, ry);
                if (hit && hit.length > 0) {
                    thisB.notifyFeatureHover(ev, hit[hit.length - 1], hit, tier);
                }
            }, 1000);
        }

Is there a reason for this 1 second delay in hover events? When using this feature in the browser, it seems like the application is horribly slow and laggy.

The initial motivation for the delay was because the original request that prompted this API was about opening popups when hovering a feature -- and for that, you do want to distinguish between a true "hover" (point and wait) and a pointer over a feature.

c41f68d29caabed84078a80ea42ddb5d7f51a113 adds an extra option when registering a hover listener:

    browser.addFeatureHoverListener(listenerFunction, {immediate: true});

...with this option, your listeners will be notified every time the feature(s) under the pointer change.

Does this help?

A lot! thank you.
