[O] face for inline-tasks

[Andreas Leha]

Hi all,

how can I achieve, that the whole inline-task uses a font face
(esp. with background)?

I customized the face org-inlinetask, but that only fontifies the last
stars and the 'END'.  I would like to color the whole line plus all the
contents.  I have similar settings for my code blocks and find it very
convenient.
(see http://orgmode.org/worg/images/color-themes/color-theme-leuven.png
for an example of what I mean)

Is that possible for inline-tasks, as well?

Best,
Andreas
