Fixed bugs 2570, 3145, improved OpenGL ES context support on Windows and X11

Mark Callow

The attached patch does the following for the X11 and Windows platforms, the only ones where SDL attempts to use context_create_es_profile:

- Adds SDL_HINT_OPENGL_ES_DRIVER by which the application can
say to use the OpenGL ES driver & EGL rather than the Open GL
driver. (For bug #2570)
- Adds code to {WIN,X11}_GL_InitExtensions to determine the maximum
OpenGL ES version supported by the OpenGL driver (for bug #3145)
- Modifies the test that determines whether to use the OpenGL
driver or the real OpenGL ES driver to take into account the
hint, the requested and supported ES version and whether ES 1.X
is being requested. (For bug #2570 & bug #3145)
- Enables the testgles2 test for __WINDOWS__ and __LINUX__ and adds
the test to the VisualC projects.

With the fix in place I have run testdraw2, testgl and testgles2 without any issues and have run my own apps that use OpenGL, OpenGL ES 3 and OpenGL ES 1.1.

# These exist entirely to fool aclocal when bootstrapping libtool.

# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
slouken@3342
    15
# which have later been changed to m4_define as they aren't part of the
slouken@3342
    16
# exported API, or moved to Autoconf or Automake where they belong.
slouken@3342
    17

    18
# The trouble is, aclocal is a bit thick.  It'll see the old AC_DEFUN
slouken@3342
    19
# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
slouken@3342
    20
# using a macro with the same name in our local m4/libtool.m4 it'll
slouken@3342
    21
# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
slouken@3342
    22
# and doesn't know about Autoconf macros at all.)
slouken@3342
    23
#
slouken@3342
    24
# So we provide this file, which has a silly filename so it's always
slouken@3342
    25
# included after everything else.  This provides aclocal with the
slouken@3342
    26
# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
slouken@3342
    27
# because those macros already exist, or will be overwritten later.
slouken@3342
    28
# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6. 
slouken@3342
    29
#
slouken@3342
    30
# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
slouken@3342
    31
# Yes, that means every name once taken will need to remain here until
slouken@3342
    32
# we give up compatibility with versions before 1.7, at which point
slouken@3342
    33
# we need to keep only those names which we still refer to.
slouken@3342
    34
slouken@3342
    35
# This is to help aclocal find these macros, as it can't see m4_define.
