-<!-- A function is generated from a template.  Multiple functions can be

-     generated from a single template with different arguments.  For example,

-     glColor3f can be generated from

-

-     <function name="Color3f" template="Color" gltype="GLfloat" vector_size="3" expand_vector="true"/>

-

-     and glColor4iv can be generated from

-

-     <function name="Color4iv" template="Color" gltype="GLint" vector_size="4"/>

-

-     In a template, there are <desc>s that describe the properties of

-     parameters.  A <desc> can enumerate the valid values of a parameter.  It

-     can also specify the error code when an invalid value is given, and etc.

-     By nesting <desc>s, they can create dependency between parameters.

-

-     A function can be marked as external.  It means that the function cannot

-     be dispatched to the corresponding mesa function, if one exists, directly,

-     and requires an external implementation.

+<!-- A function is generated from a template.  Multiple functions can be
+     generated from a single template with different arguments.  For example,
+     glColor3f can be generated from
+
+     <function name="Color3f" template="Color" gltype="GLfloat" vector_size="3" expand_vector="true"/>
+
+     and glColor4iv can be generated from
+
+     <function name="Color4iv" template="Color" gltype="GLint" vector_size="4"/>
+
+     In a template, there are <desc>s that describe the properties of
+     parameters.  A <desc> can enumerate the valid values of a parameter.  It
+     can also specify the error code when an invalid value is given, and etc.
+     By nesting <desc>s, they can create dependency between parameters.
+
+     A function can be marked as external.  It means that the function cannot
+     be dispatched to the corresponding mesa function, if one exists, directly,
+     and requires an external implementation.

- * Functions for allocating/managing renderbuffers.

- * Also, routines for reading/writing software-based renderbuffer data as

- * ubytes, ushorts, uints, etc.

- *

- * The 'alpha8' renderbuffer is interesting.  It's used to add a software-based

- * alpha channel to RGB renderbuffers.  This is done by wrapping the RGB

- * renderbuffer with the alpha renderbuffer.  We can do this because of the

- * OO-nature of renderbuffers.

- *

- * Down the road we'll use this for run-time support of 8, 16 and 32-bit

- * color channels.  For example, Mesa may use 32-bit/float color channels

- * internally (swrast) and use wrapper renderbuffers to convert 32-bit

- * values down to 16 or 8-bit values for whatever kind of framebuffer we have.
