svgalib has its own mouse driver.  I forgot about that.

I forgot you also need libX11 which is 767K for BL2

X is larger and X programs are probably GUI and therefore larger.
Numbers are for BL2 X and svgalib (1.4.3).


xv is 1.15 MB                   zgv is 213K             seejpeg 100K

Their dependencies are shared among multiple programs:

libX11 - 767K			libvgagl 54K 
Xvesa - 870K static		libvga	331K		libvga 331K
(call it 600 if dynamic TinyX)  libjpeg 127K
                                libpng  158K
                                libtiff 180K
                                libz     62K

Total >= 2.5MB                             1.124MB           431K

If you want to save space, convert png and tiff to ppm using netpbm 
programs and view with seejpeg.  A 24-bit photo looks the same to me with 
seejpeg as with zgv.  A little trickier configuring links or lynx to view 
images with seejpeg after first converting to pnm.

pngtopnm 17K   - much smaller than libpng
tifftopnm 22K                 or libtiff

To flip use pnmflip 2.5K or pamflip 12K or pnmrotate 10K (to 180 degrees)

seejpeg will do slideshows, greyscale, stretching, centering
Views jpeg gif ppm bmp targa

zgv has lots of extras - zoom, reduce, change colors, brightness, bold 
text, thumbnails, animated gifs, fancy cursor.....

Much of the above can be done by netpbm programs instead, to convert 
rather than just view changes.

xli does not view ppm.  I don't have it in BL2 to analyze.
