/**
* Create the \c GL_RENDERER string for DRI drivers.
* 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 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 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.
+ * 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 visType GLX visual type. Usually either \c GLX_TRUE_COLOR or
- * \c GLX_DIRECT_COLOR.
- *
+ * \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.
+ * \param mutable_render_buffer Enable __DRI_ATTRIB_MUTABLE_RENDER_BUFFER,
+ * which translates to
+ * EGL_MUTABLE_RENDER_BUFFER_BIT_KHR.
+ *
* \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.
+ * 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).
