Patch for floating layer

[dov]

Hello,

Thanks a lot for the freetype plugin! I created a patch that makes
the resulting text layer a floating layer instead of a normal layer.
The patch also checks if there was is a selection active in which
case it will center the resulting text within the selection.

Perhaps you would like to have another checkbutton for the user to
decide if she wants a normal layer or a floating layer. I'll leave
that up to you to decide.

Another issue that I am looking into is why in some Hebrew ttf fonts
all the characters are mapped into font position '0'. But if I press
[Font Table] I do see all the rendered characters of the font. There
must be some mapping somewhere that gets screwed up. I'll let you
know on this mailing list know if I find something.

Regards,
Dov
