Heat layer is not changed when working with many points.

[divinocfelix]

Good afternoon.

I am building a dynamic heat map using elasticsearch, so the amount of points can vary according to the precision reported by the user, but when I have a lot of points I can not see changes on the map.

By doing some tests, I saw that the latLngToContainerPoint function in the leaflet.js file converts different data to the same point on the map, making a considerable reduction in the number of points that are drawn, thus not allowing the map to be wide.
An example is the data below, which are converted to the same point (x = 500, y = 400)

[-19.9155, -43.94, 1115]
[-19.921, -43.94, 933]

Obs.
1 The problem can be verified using the examples map1 and map2.
2. In map2, the function that constructs the heat layer (_createHeatLayer) is only using 1/3 of the points, so that the change in the heat layer becomes noticeable.
3º To simulate the problem open the files map1 is map2, then click add and subtract precision.

Example
Map1 - precision 8

Map2 - precision 8
