/** This class contains a generated list of OpenGL extension functions, which are either dynamically loaded
for a specific GL context, or simply call-through to the appropriate OS function where available.
This class is provided for backwards compatibility. In new code, you should prefer to use
functions from the juce::gl namespace. By importing all these symbols with
`using namespace ::juce::gl;`, all GL enumerations and functions will be made available at
global scope. This may be helpful if you need to write code with C source compatibility, or
which is compatible with a different extension-loading library.
All the normal guidance about `using namespace` should still apply - don't do this in a header,
or at all if you can possibly avoid it!
