-<!-- 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.

+
+ 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.
