/*
    Modifications by Max Lyons (maxlyons@erols.com):

    March 4, 2002.  Changes made to mymalloc and myfree functions to
    work around a problem allocating more than 256MB of RAM from heap.
    See Microsoft Knowledge Base article Q198959 for more information.
    "PRB: Windows 95/98 Heaps Have A 255.9 MB Allocation Ceiling".

    This problem was causing "out of memory" errors when trying to stitch
    images that require more than 256MB of RAM (i.e. 64 megapixels)
    to be requested using the mymalloc function.

    March 6, 2002.  Added memory monitoring feature...
    This feature reports on memory allocation requests (i.e. chunks of memory
    that Pano Tools request from the operating system), and total memory
    usage (the sum of all currently allocated memory).
    This information is displayed on the progress dialog.

/* modified by Fulvio Senore June.2004

Added a call to disable warnings from the TIFF library: some tiff files (probably created by Photoshop)
caused annoying warnings about unknown tags while loading each tiff source image
