bool OpenGLSdlGraphicsManager::createOrUpdateGLContext ( uint  gameWidth,
uint  gameHeight,
uint  effectiveWidth,
uint  effectiveHeight,
bool  renderToFramebuffer 
) [protected]

Initialize an OpenGL window matching as closely as possible the required properties.

When unable to create a context with anti-aliasing this tries without. When unable to create a context with the desired pixel depth this tries lower values.
