-<H1>Mesa 7.11 Release Notes / (release date TBD)</H1>
-
-<p>
-Mesa 7.11 is a new development release.
-People who are concerned with stability and reliability should stick
-with a previous release or wait for Mesa 7.11.1.
-</p>
-<p>
-Mesa 7.11 implements the OpenGL 2.1 API, but the version reported by
-glGetString(GL_VERSION) depends on the particular driver being used.
-Some drivers don't support all the features required in OpenGL 2.1.
-</p>
-<p>
-See the <a href="install.html">Compiling/Installing page</a> for prerequisites
-for DRI hardware acceleration.

-/**
- * The GL texture image functions in teximage.c basically just do
- * error checking and data structure allocation. They in turn call
- * device driver functions which actually copy/convert/store the user's
- * texture image data.
- *
- * However, most device drivers will be able to use the fallback functions
- * in this file. That is, most drivers will have the following bit of
- * code:
- * ctx->Driver.TexImage1D = _mesa_store_teximage1d;
- * ctx->Driver.TexImage2D = _mesa_store_teximage2d;
- * ctx->Driver.TexImage3D = _mesa_store_teximage3d;
- * etc...
- *
- * Texture image processing is actually kind of complicated. We have to do:
- * Format/type conversions
- * pixel unpacking
- * pixel transfer (scale, bais, lookup, etc)
- *
- * These functions can handle most everything, including processing full
- * images and sub-images.
