Overview of Queried Function Groups
This section contains an overview of all the function groups available
via the SciTech SNAP Graphics Architecture API. Unlike the global
functions, these functions are not called directly, but instead are
called via groups of function pointers that are returned by the GA_queryFunctions function.
As such each function group is relative to the specific group of
functions that the function pointer belongs in. In the detailed
function reference section, these functions are actually documented in
the data structures section, underneath the named data structure
containing the function pointers themselves.
