Tomas Burleigh d524d46969 WebGLPointsLayer wrapX support - partially addressing #11131 ...

WebGLPointsLayer renderFrame and renderHitDetection will now draw
multiple worlds if the source and projection support wrapX.

Hit detection needs additional improvement. It stops working after
more than one wrap around the world. If 0 is the middle world, then
the hit detection works for worlds -1, 0, and -1, but not for worlds
> 2 or < -2.

The example has hit detection enabled, demonstrated with a colour
change on hover for the circle styles. When moving the mouse, the hit
detection is unreliable and flickers on/off. This needs improvement.

The webgl-points renderer test has been updated.
