• Add Map getConfigProperty method for getting current style config values.
• Add config support in terrain options.
• Improve performance for pitched views with many fill extrusions on higher zoom levels.
• Allow turning off the terrain that is defined in the imports on the root-level Style by setting it to null.
• Allow the partial terrain exaggeration update without specifying the source.
• Respect style schema restrictions (minValue, maxValue, stepValue, values, type) when evaluating config options.
