/*
Function: gdFree
Frees memory that has been allocated by libgd functions.
Unless more specialized functions exists (for instance, <gdImageDestroy>),
all memory that has been allocated by public libgd functions has to be
freed by calling <gdFree>, and not by free(3), because libgd internally
doesn't use alloc(3) and friends but rather its own allocation functions,
which are, however, not publicly available.
Parameters:
ptr - Pointer to the memory space to free. If it is NULL, no operation is
performed.
Returns:
Nothing.
