font_factor

[Johannes Hofmann]

In styleengine, we use font_factor for calculation of larger and x-small
and so forth, but we don't apply it when given an ordinary font size like
11px.

Just to double-check: That's not intended behaviour, right?

sorry for the delay...
This is intentional, but we know that there is a usability issue.
In CSS px, mm, pt etc. define absolute sizes [1].
So if we want to adhere to the CSS spec strictly I think we can't
just scale them.
On the other hand web designers just use px without thinking about
the implications. Also other browsers allow scaling of those fonts
afaik.
I think we have the following options:

* ignore CSS and apply font_factor also to absolute font sizes
* implement a zoom feature that displays everything larger (also
images etc.
* check other browsers for more alternatives

Applying font_factor seems much more usable to me.

A zoom feature would be cool, though. I wonder whether there's some
level where we could get cheap and halfway tolerable zooming by
throwing some of fltk's matrix transformation stuff at what we're
drawing.

I'd apply font_factor, especially if that's what other browsers do.

Scaling images may hurt (think of PDAs).
An image_factor may help for those (just a wild thought).

Should check before making a decision.

My Firefox has a zoom option, that zooms all text and images and
an additional option to zoom text only.

I also tend to a apply font_factor to all text.
