+This directory is a collection of function which may be useful to
+OpenGL/Mesa programmers.
+
+
+errcheck.c - an OpenGL error check/report function
+glutskel.c - handy skeleton for GLUT programs
+idproj.c - setup an identity projection
+mwmborder.c - remove Motif window decoration/border
+winpos.c - set absolute window raster position
+readtex.c - load textures/mipmaps from an .rgb file
+showbuffer.[ch] - show depth, alpha, or stencil buffer contents
+glstate.[ch] - query/print GL state variables, for debugging, etc.
+sampleMakefile - example Makefile for making OpenGL/Mesa apps on Unix
+dumpsate.c - dump all OpenGL state, from Stephane Rehel
+imagesgi.cpp,.h - read SGI image files
+
+
+more to come...

+ * Date: Mon, 31 May 1999 18:40:54 -0400
+ * To: Paul Brian <[email protected]>
+ * Subject: OpenGL State Dump Function
+ *
+ * Here is a function that dumps the current OpenGL state. I wrote it
+ * some time ago.
+ *
+ * In the attachment:
+ * + the code itself
+ * + its output
+ *
+ * I think Mesa is wrong on some getBooleanv(). For example, GL_VERTEX_ARRAY
+ * is queried by IsEnabled() (cf. p. 196 of the spec). But on page 193
+ * we can read that all the boolean attribs that can be queried by IsEnabled()
+ * can also be queried by IsEnabled().
+ *
+ * I had duplicated all the enums (LOCAL_*) so that the code can run on any
+ * OpenGL version, even if an enum is not recognized.
+ *
+ * The code can be shipped in the public domain.
+ *
+ * Stephane.

+/******************************************************************************
+** Filename : imageSgi.cpp
+** UNCLASSIFIED
+**
+** Description : Utility to read SGI image format files. This code was
+** originally a SGI image loading utility provided with the
+** Mesa 3D library @ http://www.mesa3d.org by Brain Paul.
+** This has been extended to read all SGI image formats
+** (e.g. INT, INTA, RGB, RGBA).
+**
+** Revision History:
+** Date Name Description
+** 06/07/99 BRC Initial Release
+**
+** Note:
+**
+** The SGI Image Data (if not RLE)
+**
+** If the image is stored verbatim (without RLE), then image data directly
+** follows the 512 byte header. The data for each scanline of the first
+** channel is written first. If the image has more than 1 channel, all
+** the data for the first channel is written, followed by the remaining
+** channels. If the BPC value is 1, then each scanline is written as XSIZE
+** bytes. If the BPC value is 2, then each scanline is written as XSIZE
+** shorts. These shorts are stored in the byte order described above.
