/* FIXME: consider if we should change the code that uses these. 20070316 pederb. */
/* (Why? --mortene.) */

/*

  We need to decide if we're going to use the _ARB versions of the
  defines or if we're going to just skip using the _ARB postfix. Most (all?)
  example code are using the _ARB postfix, so it might be a bit confusing if
  the OpenGL code in Coin doesn't use it.

  I feel we should supply the _ARB versions of the defines, since
  that's what everybody is using, and glext.h (supplied by Mesa and
  nVidia) also use _ARB. The problem is when an ARB is taken in as
  part of the OpenGL standard. We then might have to supply both
  versions of the defines.

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
