From 6024168ef21dd4fe6c5ddd7e837d56076e886e01 Mon Sep 17 00:00:00 2001 From: Bruno de Oliveira Abinader Date: Tue, 28 Feb 2017 18:26:19 -0800 Subject: Mapbox GL native circle support Circles crossing one pole are drawn inverted. Circles crossing 2 poles do not even have the correct geometry. Nevertheless, a first approximation.
