Style files are currently limited to the following syntax only:

widgetclassname =3D { style_entry : { value(s) } }

This makes it currently impossible to use anything else besides
a) the widget class names and non-variable arguments/values
b) the 'import ocempgui.widgets.Constants' directive.

So using an 'import foo' or 'from bar import *' is likely to fail as
well as variable definitions and assignments are.=20
Yep, pretty lousy when it comes to such cases at the moment. There were
other priorities when 0.1.x was developed and only a minimum set of
necessities for a runtime style handling (give me a few more days for
other clumsy excuses here ;-).
I guess, that should become a necessary task for 0.2.x. If this is a
show stopper for you however, tell me and I'll make up a fix for that in
a few days.

Not without implementing an own draw() method for the specified widget
in 0.1.x and some tweaks here and there. 0.2.x will have limited support
for that due to its different background handling (if you want more
details on that issue and how that stuff is currently done, please tell
me).

Override the ImageButton's draw() method in your own ImageButton
implementation or set up an own Style object with your specific
draw_imagebutton() method and bind it to the base.GlobalStyle
variable. More details on that and a short example can be found in the
manual. If you do so, I recommend you to look at the code in
Style.draw_imagebutton() and ImageButton.draw() to get a quick overview,
how it is currently done. Basically you just have to modify the blitting
rectangle values for the text.
