+ * <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.

+ * Mesa context/visual/framebuffer management functions.
+ *
+ * There are three Mesa data types which are meant to be used by device
+ * drivers:
+ * - GLcontext: this contains the Mesa rendering state
+ * - GLvisual:  this describes the color buffer (RGB vs. ci), whether or not
+ *   there's a depth buffer, stencil buffer, etc.
+ * - GLframebuffer:  contains pointers to the depth buffer, stencil buffer,
+ *   accum buffer and alpha buffers.
+ *
+ * These types should be encapsulated by corresponding device driver
+ * data types.  See xmesa.h and xmesaP.h for an example.
+ *
+ * In OOP terms, GLcontext, GLvisual, and GLframebuffer are base classes
+ * which the device driver must derive from.
+ *
+ * The following functions create and destroy these data types.

+ * Adaptor/wrappers for GL_DEPTH_STENCIL renderbuffers.
+ *
+ * The problem with a GL_DEPTH_STENCIL renderbuffer is that sometimes we
+ * want to treat it as a stencil buffer, other times we want to treat it
+ * as a depth/z buffer and still other times when we want to treat it as
+ * a combined Z+stencil buffer!  That implies we need three different sets
+ * of Get/Put functions.
+ *
+ * We solve this by wrapping the Z24_S8 renderbuffer with depth and stencil
+ * adaptors, each with the right kind of depth/stencil Get/Put functions.

+/**
+ * \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
+ * - rand and RAND_MAX
+ *
+ * \note When compiled into a XFree86 module these functions wrap around
+ * XFree86 own wrappers.

+         for 2 <= u.f <= 4: 1.00 - u.f / 8
+
+         This isn't a bad approximation of 1/sqrt.  The maximum difference from
+         1/sqrt will be around .06.  After three Newton-Raphson iterations, the
+         maximum difference is less than 4.5e-8.  (Which is actually close
+         enough to make the following bias academic...)
+
+         To get a better approximation you can add a bias to the magic
+         number.  For example, if you subtract 1/2 of the maximum difference in
+         the first approximation (.03), you will get the following function:
+
+         for 1 <= u.f <= 2:    1.22 - u.f / 4
+         for 2 <= u.f <= 3.76: 0.97 - u.f / 8
+         for 3.76 <= u.f <= 4: 0.72 - u.f / 16
+         (The 3.76 to 4 range is where the result is < .5.)
+
+         This is the closest possible initial approximation, but with a maximum
+         error of 8e-11 after three NR iterations, it is still not perfect.  If
+         you subtract 0.0332281 instead of .03, the maximum error will be
+         2.5e-11 after three NR iterations, which should be about as close as
+         is possible.

+ * 1. There are 1D, 2D and 3D functions for fetching texels from texture
+ *    images, returning both GLchan values and GLfloat values.  (six
+ *    functions in total)
+ *    You don't have to provide both the GLchan and GLfloat functions;
+ *    just one or the other is OK.  Mesa will use an "adaptor" to convert
+ *    between GLchan/GLfloat when needed.
+ *    Since the adaptors have small performance penalty, we provide both
+ *    GLchan and GLfloat functions for some common formats like RGB, RGBA.
