b274a2656d tests/gears: Ensure we don't use unavailable GL resources
We need to check on realize if we have access to a GL context, before
calling GL functions. We use gtk_gl_area_get_error() for that.

We also need to tear down the resources during unrealization, instead
of leaking them.

b3725a455d test/gtkgears.c: Fix on C89 Compilers
Make sure that variables are declared at the top of the block.

Break up one of the sincos() calls into individual calls to sin() and cos()
so that we do not have to complicate the initialization of the following
GLfloat array.

17bc7aaefd Check for existence of sincos
It apparently doesn't exist everywhere.

0019eb7bf9 gears: Update to slightly more modern OpenGL
Instead of using glxgears, which still uses OpenGL 2.1 and the fixed
pipeline, we use a slightly modified es2gears, OpenGL 3.2, and the
programmable pipeline.

fbe4f94519 test/gtkgears.c: Fix Builds on Systems Without M_PI
Use G_PI in place of M_PI to fix the build on compilers that do not have
M_PI defined.

fdeb4f8c16 gl: Make gdk_gl_context_make_current() return void
Its not really reasonable to handle failures to make_current, it
basically only happens if you pass invalid arguments to it, and
thats not something we trap on similar things on the X drawing side.

If GL is not supported that should be handled by the context creation
failing, and anything going wrong after that is essentially a critical
(or an async X error).
