supported static method
Test whether the browser supports Mapbox GL JS.
@function supported
@param {boolean} failIfMajorPerformanceCaveat
=false If true
,
the function will return false
if the performance of Mapbox GL JS would
be dramatically worse than expected (e.g. a software WebGL renderer would be used).
@return {boolean}
@example
mapboxgl.supported() // = true
@see Check for browser support
Implementation
external static bool supported(bool failIfMajorPerformanceCaveat);
