Scale9Grid and content alignment

Question

I've just started using fb3 and while converting my fb2
project, I've come to notice that the scale9grid of the container's
skin now by default affects how the content is aligned. Although
otherwise changes to margin/padding attributes feel welcome, this
in particular makes me feel like going back to the dark ages of
html tables, where content can't overlap with the surrounding skin
parts and has to fit inside the stretching part of the skin.
Okay, pretty quickly I discovered that setting ClipContent to
false allows placing the content in relation to the container's
(and skin's) top-left corner but still, for instance, setting
content's width or height to 100% sets it's size to match the
scale9grid's inner rectangle instead of container's size.
It's still possible to hack through this by setting negative
padding values to counter the effect of the scale9 margins but it's
really a drag. Container's width and height still match the size of
the skin, not the stretching square of the scale9, so why can't the
content alignment and paddings default to this?

Answer 1

... still, setting clipContent = false is hardly a solution
if you want scrollable content... unless you add another
transparent container to clip the content and control scroll.
Here's a set of skins I've made for flex2..

Getting them right wasn't too hard although some components
still lacked ability to tweak paddings/borderThickness.. Now, I
wonder how far I can get with flex3 when it's trying to stretch the
skin each time around the content? If you look at the panel skins,
you'll notice that the skin has some graphic style behind the panel
content. The stretching gridsquare is below and to the right of
this, so the panel stretches alright, but it's obvious that I
wouldn't want the content to follow the scalegrid in any way. Only
thing the content should obey are the paddings (
'borderThicknesses' in flex2).
