From 15fdbc8361d0b865aea5e2f374b471081ed4214a Mon Sep 17 00:00:00 2001 From: Chia-I Wu Date: Fri, 17 Jul 2009 11:56:00 -0600 Subject: [PATCH] egl: Remove redundant DeletePending flag. A context or surface that is neither linked to a display nor current to a thread should be destroyed. Therefore, an unlinked context or surface implies a pending delete automatically.
