+ * \section MainIntroduction Introduction
+ *
+ * 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.
+ *

+ * - GLframebuffer: contains pointers to the depth buffer, stencil buffer,

+ * These types should be encapsulated by corresponding device driver

+/**
+ * \file imports.c
+ * Standard C library function wrappers.
+ *
+ * Imports are services which the device driver or window system or
+ * operating system provides to the core renderer. The core renderer (Mesa)
+ * will call these functions in order to do memory allocation, simple I/O,
+ * etc.
+ *
+ * Some drivers will want to override/replace this file with something
+ * specialized, but that'll be rare.
+ *
+ * Eventually, I want to move roll the glheader.h file into this.
+ *
+ * The OpenGL SI's __GLimports structure allows per-context specification of
+ * replacements for the standard C lib functions. In practice that's probably
+ * never needed; compile-time replacements are far more likely.
+ *
+ * The _mesa_*() functions defined here don't in general take a context
+ * parameter. I guess we can change that someday, if need be.
+ * So for now, the __GLimports stuff really isn't used.
+ *
+ * \todo Functions still needed:
+ * - scanf
+ * - qsort
+ * - bsearch
+ * - rand and RAND_MAX
+ *
+ * \note When compiled into a XFree86 module these functions wrap around
+ * XFree86 own wrappers.
