- *
- * The Mesa Main module consists of all the files in the main/ directory.
- * Among the features of this module are:
- * <UL>
- * <LI> Structures to represent most GL state </LI>
- * <LI> State set/get functions </LI>
- * <LI> Display lists </LI>
- * <LI> Texture unit, object and image handling </LI>
- * <LI> Matrix and attribute stacks </LI>
- * </UL>
- *
- * Other modules are responsible for API dispatch, vertex transformation,
- * point/line/triangle setup, rasterization, vertex array caching,
- * vertex/fragment programs/shaders, etc.

- * There are three large Mesa data types/classes which are meant to be

- * - struct gl_context: this contains the Mesa rendering state
- * - struct gl_config: this describes the color buffer (RGB vs. ci), whether or not

- * These types should be encapsulated by corresponding device driver

- *
- * In OOP terms, struct gl_context, struct gl_config, and struct gl_framebuffer are base classes

-/* This is a table driven implemetation of the glGet*v() functions.
- * The basic idea is that most getters just look up an int somewhere
- * in struct gl_context and then convert it to a bool or float according to
- * which of glGetIntegerv() glGetBooleanv() etc is being called.
- * Instead of generating code to do this, we can just record the enum
- * value and the offset into struct gl_context in an array of structs. Then
- * in glGet*(), we lookup the struct for the enum in question, and use
- * the offset to get the int we need.
- *
- * Sometimes we need to look up a float, a boolean, a bit in a
- * bitfield, a matrix or other types instead, so we need to track the
- * type of the value in struct gl_context. And sometimes the value isn't in
- * struct gl_context but in the drawbuffer, the array object, current texture
- * unit, or maybe it's a computed value. So we need to also track
- * where or how to find the value. Finally, we sometimes need to
- * check that one of a number of extensions are enabled, the GL
- * version or flush or call _mesa_update_state(). This is done by
- * attaching optional extra information to the value description
- * struct, it's sort of like an array of opcodes that describe extra
- * checks or actions.
- *
- * Putting all this together we end up with struct value_desc below,
- * and with a couple of macros to help, the table of struct value_desc
- * is about as concise as the specification in the old python script.

+/* This is a table driven implemetation of the glGet*v() functions.
+ * The basic idea is that most getters just look up an int somewhere
+ * in struct gl_context and then convert it to a bool or float according to
+ * which of glGetIntegerv() glGetBooleanv() etc is being called.
+ * Instead of generating code to do this, we can just record the enum
+ * value and the offset into struct gl_context in an array of structs. Then
+ * in glGet*(), we lookup the struct for the enum in question, and use
+ * the offset to get the int we need.
+ *
+ * Sometimes we need to look up a float, a boolean, a bit in a
+ * bitfield, a matrix or other types instead, so we need to track the
+ * type of the value in struct gl_context. And sometimes the value isn't in
+ * struct gl_context but in the drawbuffer, the array object, current texture
+ * unit, or maybe it's a computed value. So we need to also track
+ * where or how to find the value. Finally, we sometimes need to
+ * check that one of a number of extensions are enabled, the GL
+ * version or flush or call _mesa_update_state(). This is done by
+ * attaching optional extra information to the value description
+ * struct, it's sort of like an array of opcodes that describe extra
+ * checks or actions.
+ *
+ * Putting all this together we end up with struct value_desc below,
+ * and with a couple of macros to help, the table of struct value_desc
+ * is about as concise as the specification in the old python script.

- * GLGL uniform arrays and structs require special handling.
- *
- * The GL_ARB_shader_objects spec says that if you use

- * access other elements of the array by adding an offset to the
- * returned location. For example, you must call
- * glGetUniformLocation("foo[16]") if you want to set the 16th element
- * of the array with glUniform().
- *
- * HOWEVER, some other OpenGL drivers allow accessing array elements
- * by adding an offset to the returned array location. And some apps
- * seem to depend on that behaviour.
- *
- * Mesa's gl_uniform_list doesn't directly support this since each
- * entry in the list describes one uniform variable, not one uniform
- * element. We could insert dummy entries in the list for each array
- * element after [0] but that causes complications elsewhere.
- *
- * We solve this problem by encoding two values in the location that's
- * returned by glGetUniformLocation():
- * a) index into gl_uniform_list::Uniforms[] for the uniform
- * b) an array/field offset (0 for simple types)
- *
- * These two values are encoded in the high and low halves of a GLint.
- * By putting the uniform number in the high part and the offset in the
- * low part, we can support the unofficial ability to index into arrays
- * by adding offsets to the location value.

+ * b) an array/field offset (0 for simple types)
