WoooHoo!!
It took some time, but I finally did it!
I hacked the ScrollableTextLayout to support scale and rotation
properties, it's all performed at the "set_state" and "unset_state" of
the ScrollableTextLayoutGroup, I had to hook some reference attributes
between Layout and Group so I can read the anchors, sizes, lines, and
all that stuff.
I'll keep testing it, using multilines and all variations of anchor_x
and anchor_y to see if it's all fine and then post the modifications to
the group.
I was this close to drop pyglet for this project, so I wrote to the
group as a last hope.
Thanks everybody for the help!

Thanks everybody, I've having problems replying, some messages didn't
show up in the list.
anyway, I've noticed ScrollableTextLayout uses a
ScrollableTextLayoutGroup that is unique for each instance and not
shared at all.
I'm trying to hack that group to perform all the scaling, so I don't
hook up more groups and degrade performance.
I've tried using custom groups before, but it was too slow for
scrollableText, now I see why, and know how to do it right.
I'm slowly trying to code a media center software like moovida and
mediaportal, hope I can finish it before I give up.

You can apply state changes like scaling or a perspective projection
matrix with a custom group.

Hi guys,
I'm trying to perform some text scaling and I don't care it pixelates
as I scale it up, I just need the method to be fast and doesn't
regenerate the glyphs on each draw.
I also need to do it in such way that is compatible with batch
rendering, that means It doesn't have to require a opengl state change
(is it that how it's called?) like doing a glScalef() surrounded by
glPushMatrix glPopMatrix...as far as I know you can't put a lot of
text labels in a single batch and do a a glScalef on a single label of
the batch, is that right?
so, in short: how can I have 50 labels (or ScrollableTextLayout) in a
single batch, and scale 1 label of that batch without regenerating the
glyphs,I don't care if it stretches the vertex_lists and the text
looks weird and pixelated.. in fact, that is quite exactly what I'm
looking for.
any hints?? thanks!!
