Added a hint to determine whether framebuffer texture acceleration should be used, and added default behaviors for the various platforms.

54 * \brief A variable controlling how 3D acceleration is used to accelerate the SDL 1.2 screen surface.
55 *
56 * SDL can try to accelerate the SDL 1.2 screen surface by using streaming
57 * textures with a 3D rendering engine. This variable controls whether and
58 * how this is done.
59 *
60 * This variable can be set to the following values:
61 * "0" - Disable 3D acceleration
62 * "1" - Enable 3D acceleration, using the default renderer.
63 * "X" - Enable 3D acceleration, using X where X is one of the valid rendering drivers. (e.g. "direct3d", "opengl", etc.)
64 *
65 * By default SDL tries to make a best guess for each platform whether
66 * to use acceleration or not.
