Un!x, from scratch

Haven't got one, xpaint?

Un!x, tweaking

xv!!! God I love xv.

Win32, from scratch

Paint Shop Pro 4 (3 will do but it is lacking, most notably LFN support)

Win32, tweaking

LView Pro 1.D2 (the closest Win32 native to xv, yes you can run xv on NT but it's not the same)

At some point PSP decided it should be Adobe, and Lview decided it should be PSP :-(.
