 * "none" - use no acceleration. try use software (since 1.16)
 *
 * Since 1.14, it is also possible to specify some GL properties for the GL
 * window surface. This allows applications to use GLView with depth, stencil
 * and MSAA buffers with direct rendering. The new accel preference string
 * format is thus "{HW Accel}[:depth{value}[:stencil{value}[:msaa{str}]]]".

 * Accepted values for depth are for instance "depth", "depth16", "depth24".

 * "msaa_mid" and "msaa_high". The selected configuration is not guaranteed
 * and is only valid in case of GL acceleration. Only the base acceleration
 * string will be saved (e.g. "gl" or "hw").
 *
 * Full examples include:
 *
 * "gl", - try to use OpenGL
 * "hw:depth:stencil", - use HW acceleration with default depth and stencil buffers
 * "opengl:depth24:stencil8:msaa_mid" - use OpenGL with 24-bit depth,
