- * 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.

+ * 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.
