/**
* 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 format Mesa mesa_format enum describing the pixel format
* \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 __DRI_ATTRIB_SWAP_NONE, then it
* represents a single-buffered mode. Other valid
* values are \c __DRI_ATTRIB_SWAP_EXCHANGE,
* \c __DRI_ATTRIB_SWAP_COPY, and \c __DRI_ATTRIB_SWAP_UNDEFINED.
* They represent the respective GLX values as in
* the GLX_OML_swap_method extension spec.
* \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 enable_accum Add an accum buffer to the configs
* \param color_depth_match Whether the color depth must match the zs depth
* This forces 32-bit color to have 24-bit depth, and
* 16-bit color to have 16-bit depth.
*
* \returns
* Pointer to any array of pointers to the \c __DRIconfig structures created
* for the specified formats. If there is an error, \c NULL is returned.
* Currently the only cause of failure is a bad parameter (i.e., unsupported
* \c format).

* The problem, as of 2017-05-30:
* When matching a GLXFBConfig to a __DRIconfig, GLX ignores the channel

* __DRI_ATTRIB_{CHANNEL}_SIZE but ignores __DRI_ATTRIB_{CHANNEL}_MASK.
*
* EGL does not suffer from this problem. It correctly compares the
* channel masks when matching EGLConfig to __DRIconfig.
