Implemented bug #2, 117:
Date: Mon, 21 Mar 2005 12:06:14 +0100
From: Per Inge Mathisen
Subject: Re: [SDL] Outstanding patches?
The patch adds support for setting SDL_GL_SWAP_CONTROL to Windows and
X11. In Windows you can also query this enum to check that it is
working, or see what the default is - such functionality does not
exist in GLX. For more information on the standards implemented:
