- * Creates a set of \c struct gl_config that a driver will expose.
- *
- * A set of \c struct gl_config 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 struct gl_config 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 struct gl_config 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 struct gl_config. 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 msaa_samples Array of msaa sample count. 0 represents a visual
- * without a multisample buffer.
- * \param num_msaa_modes Number of entries in \c msaa_samples.
- * \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.

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.
