The stock 1.2.x version of SDL only supports regular OpenGL. The
version on WebOS is specially patched to add some extra API to request
a GLES1 or GLES2 context. This patch adds a configure check to detect
when Cogl is being built with the patched version of SDL. In that case
it will additionally allow the gles1 and gles2 drivers and set the
right video mode attributes to get the corresponding context.
