Emmanuel,

The CPU can do bittest operations several times faster than it can do string finds.

So codemine uses a programmer efficient anchor which requires more CPU time at resize time.

Europa uses a programmer inefficient anchor, although my builder removes that problem, and gains speed where the performace is most needed at resize time.

When it all boils down there are really only a handful of anchor values that are practical to use. The BuildAnchor form only needs 6 distinct anchors.

>Codemine use a string property to define resizing and it's not that slow because we now have 32 bits processor (and even 64) and lots of RAM.
>10 bits may be more efficient for a computer but not for the human. It makes a builder necessary to quickly set this new Anchor property. Anyway, thanks for providing us this builder.
