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.

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.
