+/**
+ * Creates a set of \c __GLcontextModes that a driver will expose.
+ *
+ * A set of \c __GLcontextModes will be created based on the supplied
+ * parameters. The number of modes processed will be 2 *
+ * \c num_depth_stencil_bits * \c num_db_modes.
+ *
+ * For the most part, data is just copied from \c depth_bits, \c stencil_bits,
+ * \c db_modes, and \c visType into each \c __GLcontextModes element.
+ * However, the meanings of \c fb_format and \c fb_type require further
+ * explanation. The \c fb_format specifies which color components are in
+ * each pixel and what the default order is. For example, \c GL_RGB specifies
+ * that red, green, blue are available and red is in the "most significant"
+ * position and blue is in the "least significant". The \c fb_type specifies
+ * the bit sizes of each component and the actual ordering. For example, if
+ * \c GL_UNSIGNED_SHORT_5_6_5_REV is specified with \c GL_RGB, bits [15:11]
+ * are the blue value, bits [10:5] are the green value, and bits [4:0] are
+ * the red value.
+ *
+ * One sublte issue is the combination of \c GL_RGB or \c GL_BGR and either
+ * of the \c GL_UNSIGNED_INT_8_8_8_8 modes. The resulting mask values in the
+ * \c __GLcontextModes structure is \b identical to the \c GL_RGBA or
+ * \c GL_BGRA case, except the \c alphaMask is zero. This means that, as
+ * far as this routine is concerned, \c GL_RGB with \c GL_UNSIGNED_INT_8_8_8_8
+ * still uses 32-bits.
+ *
+ * If in doubt, look at the tables used in the function.
+ *
+ * \param ptr_to_modes Pointer to a pointer to a linked list of
+ * \c __GLcontextModes. Upon completion, a pointer to
+ * the next element to be process will be stored here.
+ * If the function fails and returns \c GL_FALSE, this
+ * value will be unmodified, but some elements in the
+ * linked list may be modified.
+ * \param fb_format Format of the framebuffer. Currently only \c GL_RGB,
+ * \c GL_RGBA, \c GL_BGR, and \c GL_BGRA are supported.
+ * \param fb_type Type of the pixels in the framebuffer. Currently only
+ * \c GL_UNSIGNED_SHORT_5_6_5,
+ * \c GL_UNSIGNED_SHORT_5_6_5_REV,
+ * \c GL_UNSIGNED_INT_8_8_8_8, and
+ * \c GL_UNSIGNED_INT_8_8_8_8_REV are supported.
+ * \param depth_bits Array of depth buffer sizes to be exposed.
+ * \param stencil_bits Array of stencil buffer sizes to be exposed.
+ * \param num_depth_stencil_bits Number of entries in both \c depth_bits and
+ * \c stencil_bits.
+ * \param db_modes Array of buffer swap modes. If an element has a
+ * value of \c GLX_NONE, then it represents a
+ * single-buffered mode. Other valid values are
+ * \c GLX_SWAP_EXCHANGE_OML, \c GLX_SWAP_COPY_OML, and
+ * \c GLX_SWAP_UNDEFINED_OML. See the
+ * GLX_OML_swap_method extension spec for more details.
+ * \param num_db_modes Number of entries in \c db_modes.
+ * \param visType GLX visual type. Usually either \c GLX_TRUE_COLOR or
+ * \c GLX_DIRECT_COLOR.
+ *
+ * \returns
+ * \c GL_TRUE on success or \c GL_FALSE on failure. Currently the only
+ * cause of failure is a bad parameter (i.e., unsupported \c fb_format or
+ * \c fb_type).
+ *
+ * \todo
+ * There is currently no way to support packed RGB modes (i.e., modes with
+ * exactly 3 bytes per pixel) or floating-point modes. This could probably
+ * be done by creating some new, private enums with clever names likes
+ * \c GL_UNSIGNED_3BYTE_8_8_8, \c GL_4FLOAT_32_32_32_32,
+ * \c GL_4HALF_16_16_16_16, etc. We can cross that bridge when we come to it.
