Date: Sat, 30 Aug 2003 16:28:10 +0300 From: "Mike Gorchak" Subject: Re: SDL 1.2.6 - minor changes about shared library building under QNX6 into README.QNX - added forgotten libSDLmain.a into distribution, SDL.qpg.in - added header guards to the all headers. - fixed fullscreen double buffered mode. - fixed Photon crashes after/during using fullscreen OpenGL modes. - added GL_MakeCurrent function. - added SDL_VIDEOEXPOSE event, when OpenGL window have been resized - added more HAVE_OPENGL checks to avoid dead code compilation without using OpenGL - finished code reorganization (began into previous patches).
