Raw Blame History

From f83fcf1991afad6d9c15546b2ccd775dad4e314c Mon Sep 17 00:00:00 2001
From: Jussi Kukkonen <jussi.kukkonen@intel.com>
Date: Tue, 21 Jun 2016 15:11:39 +0300
Subject: [PATCH] Add --disable-opengl configure option
--disable-opengl will remove the dependency on libepoxy and on the
OpenGL APIs. This is useful for those who want to keep using gtk+3
without the "opengl" distro feature.
GtkGLArea is still part of the API (it just doesn't work) even when
OpenGL is disabled. GdkX11GLContext was removed from the Gtk API
completely: that object exposes GL API elements so it had to be at
the very least modified.
The patch is _not_ great from a maintenance point of view and
modifying the library API is also a fairly nasty thing to do.
Next long term release (4.0) will require alternative solutions
as it actually will depend on OpenGL.
Upstream-Status: Inappropriate [Evil eye expected from upstream]
