+        https://bugs.webkit.org/show_bug.cgi?id=35759
+
+        When HW comp is turned off with the runtime flag, WebGL would still
+        create a context, but silently fail to render. This prevents that.
+        Now if HW comp is turned off getContext('webgl') will return null.

+        This allows WebGL to work on Leopard without the fix. It exposes these users to the crash
