98 * Creates a set of \c struct gl_config that a driver will expose.
99 *
100 * A set of \c struct gl_config will be created based on the supplied
101 * parameters. The number of modes processed will be 2 *
102 * \c num_depth_stencil_bits * \c num_db_modes.
103 *
104 * For the most part, data is just copied from \c depth_bits, \c stencil_bits,
105 * \c db_modes, and \c visType into each \c struct gl_config element.
106 * However, the meanings of \c fb_format and \c fb_type require further
107 * explanation. The \c fb_format specifies which color components are in
108 * each pixel and what the default order is. For example, \c GL_RGB specifies
109 * that red, green, blue are available and red is in the "most significant"
110 * position and blue is in the "least significant". The \c fb_type specifies
111 * the bit sizes of each component and the actual ordering. For example, if
112 * \c GL_UNSIGNED_SHORT_5_6_5_REV is specified with \c GL_RGB, bits [15:11]
113 * are the blue value, bits [10:5] are the green value, and bits [4:0] are
114 * the red value.
115 *
116 * One sublte issue is the combination of \c GL_RGB or \c GL_BGR and either
117 * of the \c GL_UNSIGNED_INT_8_8_8_8 modes. The resulting mask values in the
118 * \c struct gl_config structure is \b identical to the \c GL_RGBA or
119 * \c GL_BGRA case, except the \c alphaMask is zero. This means that, as
120 * far as this routine is concerned, \c GL_RGB with \c GL_UNSIGNED_INT_8_8_8_8
121 * still uses 32-bits.
122 *
123 * If in doubt, look at the tables used in the function.
124 *
125 * \param ptr_to_modes Pointer to a pointer to a linked list of
126 * \c struct gl_config. Upon completion, a pointer to
127 * the next element to be process will be stored here.
128 * If the function fails and returns \c GL_FALSE, this
129 * value will be unmodified, but some elements in the
130 * linked list may be modified.
131 * \param format Mesa mesa_format enum describing the pixel format
132 * \param depth_bits Array of depth buffer sizes to be exposed.
133 * \param stencil_bits Array of stencil buffer sizes to be exposed.
134 * \param num_depth_stencil_bits Number of entries in both \c depth_bits and
135 * \c stencil_bits.
136 * \param db_modes Array of buffer swap modes. If an element has a
137 * value of \c GLX_NONE, then it represents a
138 * single-buffered mode. Other valid values are
139 * \c GLX_SWAP_EXCHANGE_OML, \c GLX_SWAP_COPY_OML, and
140 * \c GLX_SWAP_UNDEFINED_OML. See the
141 * GLX_OML_swap_method extension spec for more details.
142 * \param num_db_modes Number of entries in \c db_modes.
143 * \param msaa_samples Array of msaa sample count. 0 represents a visual
144 * without a multisample buffer.
145 * \param num_msaa_modes Number of entries in \c msaa_samples.
146 * \param enable_accum Add an accum buffer to the configs
147 * \param color_depth_match Whether the color depth must match the zs depth
148 * This forces 32-bit color to have 24-bit depth, and
149 * 16-bit color to have 16-bit depth.
150 *
151 * \returns
152 * Pointer to any array of pointers to the \c __DRIconfig structures created
153 * for the specified formats. If there is an error, \c NULL is returned.
154 * Currently the only cause of failure is a bad parameter (i.e., unsupported
155 * \c format).
