From: Chia-I Wu Date: Mon, 3 Aug 2009 17:34:37 +0000 (-0600) Subject: egl: Replace IsBound by a pointer to the binding. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=07ee01365a8bddf6f50821ecd585784498a25ff0;p=mesa.git egl: Replace IsBound by a pointer to the binding. IsBound tells if a context or surface is current. What it does not tell is, to which thread a context is current, or to which context a surface is current. This commit replaces IsBound by a pointer to the binding thread or context.
