cairo-slides.xsl only draws correctly one (or the first) <slide> in
<slides>.

PROBLEM
The problem is with the preceding:: axis in template 'text_y'. On
every slide after the first one, the preceding:: axis grabs all
previous elements (including from earlier slides) in order to do
vertical placement calculation. Slide 2 ends up starting where slide 1
ended off instead of back at the top. This will create a problem even
when targeting only one slide as long as there are multiple slides
above the targeted slide [see workaround].

SOLUTION
Vertical position should only be dependent on elements within the same
<slide>. When this is fixed, all slides (if all displayed together)
should appear stacked on top of one another instead of top-to-bottom
(like a really long page) as they are now.

WORKAROUND
The workaround right now is to create one file: slides.xml, and then
split each slide up into its own file: slide01.xml, slide02.xml,
etc. with each file containing its slide in slides, as

<slides title="presentation title">
	<slide title="slide 2 title">
		<!-- slide 2 content -->
	</slide>
</slides>

This is kind of a pain, and could be automated, but eventually should
be fixed.

cairo-slides.xsl is hard-coded (in some places) for dimensions:
1024x768

PROBLEM
Parts of the main slide template (cairo logo, fd.o logo, title) in
cairo-slides.xsl are hard-coded for the originally designed
dimensions: 1024x768.

SOLUTION
This could be fixed by converting these to calculated values based on
one or both of the variables: $slide_width, $slide_height. It's not a
huge deal (right now font-size is explicitly specified in slides.xml,
so the author is already targeting dimensions), but it does keep one
from simply changing the $slide_width and $slide_height variables and
having everything just show up nicely
