From 00a10e8eb39526df06779e0cdb6e6871752934d7 Mon Sep 17 00:00:00 2001 From: Romain Guy Date: Mon, 26 Mar 2012 16:45:05 -0700 Subject: Use a status_t return type for GL functors WebView needs more fine-grained control over the behavior of the framework upon execution of the display lists. The new status_t allows WebView to requests its functor to be re-executed directly without causing a redraw of the entire hierarchy.
