NAME
    GetGBuffers -- Attempt to allocate ALL buffers of an entire animob.

SYNOPSIS
    status = GetGBuffers(anOb, rp, db)
    D0                   A0    A1  D0

    BOOL GetGBuffers(struct animob *, struct rastport *, bool);

FUNCTION
    For each sequence of each component of the animob, allocate memory for:
        SaveBuffer
        BorderLine
        CollMask and ImageShadow (point to same buffer)
        if db is set TRUE (user wants double-buffering) allocate:
            dbufpacket
            BufBuffer

INPUTS
    anOb = pointer to the animob structure
    rp   = pointer to the current rastport
    db   = double-buffer indicator (set TRUE for double-buffering)

RESULT
    status = TRUE if the memory allocations were all successful, else FALSE

BUGS
    If any of the memory allocations fail it does not free the partial
    allocations that did succeed.
