/*
Function: gdImageGifAnimAddPtr
Like <gdImageGifAnimAdd> (which contains more information) except
that it stores the data to write into memory and returns a pointer
to it.
This memory must be freed by the caller when it is no longer
needed. **The caller must invoke <gdFree>(), not free(),** unless
the caller is absolutely certain that the same implementations of
malloc, free, etc. are used both at library build time and at
application build time (but don't; it could always change).
The 'size' parameter receives the total size of the block of
memory.
Parameters:
im - The image to add.
size - Output: the size of the resulting buffer.
LocalCM - Flag. If 1, use a local color map for this frame.
LeftOfs - Left offset of image in frame.
TopOfs - Top offset of image in frame.
Delay - Delay before next frame (in 1/100 seconds)
Disposal - MODE: How to treat this frame when the next one loads.
previm - NULL or a pointer to the previous image written.
Returns:
Pointer to the resulting data or NULL if an error occurred.
