I have to display images with a few controls: alpha channel,
rotation, scaling, cropping. Generally it should be png but I
want to be able to handle many images. The images will be memory
based(I'll load the file in to memory then) and will be displayed
in a drawing area.
Any ideas how to go
In order to know where to split, it really has to do it from
the front. If it starts from the back, you won't necessarily
split in the same places as when iterating from the front, and
that would violate how bidirectional ranges are supposed to
work (the elements should be the same - just in

It's easy to overlook, but documentation for splitter starts
out:
Lazily splits a range using an element as a separator.
An element of a string
For "a.b.c"splitter(x), Range r is a string, r.front is a
char. The template can only be instantiated if the predicate
function is valid. The predicate function is "a == b". Since
r.front is a char, then s must be a type that can be compared
with '=='. A string and char cannot be compared with
