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

+ XHTML elements: ul, li, div. SVG content can be positioned absolutely or
+ in the vertical flow. See README for more details.

+ cairo-slides
+ ------------
+ cairo-slides is an XSLT (Extensible Stylesheet Language Transformation)
+ file. It transforms a content XML file into a nice cairo SVG slide. The
+ content XML file should be in the following format:
+ 
+ <?xml version="1.0" ?>
+ <slides title="presentation title">
+ 	<slide title="slide title" font-size="40" line-height="1.5">
+ 		<div>
+ This text starts off the slide</div>
+ 		<ul>
+ 			<li>Bullet 1</li>
+ 			<li>Bullet 2</li>
+ 			<li bullet="off">continued text from bullet 2</li>
+ 		</ul>
+ 		<div align="center" font-size="30">
+ 			This text will follow the bulleted list
+ 			and will be centered on the slide.
+ 		</div>
+ 		<g transform="translate(650, 100)">
+ 			<circle cx="0" cy="0" r="50" fill="lightGreen" />
+ 		</g>
+ 		<div>
+ 			<g>
+ 				<circle cx="0" cy="0" r="50" fill="lightBlue" />
+ 			</g>
+ 		</div>
+ 	</slide>
+ </slides>
+ 
+ (NOTE: The current version of cairo-slides can only handle one slide per
+ file. See BUGS for more info.)
+ 
+ The <slide> element can contain any svg (wrapped in a <g> group) and
+ (so far) three XHTML elements (with limited attributes).
+ 
+ Supported SVG Elements: g, (all others, placed in a <g>)
+ <g>
+ 	An SVG chunk can be added by way of the <g> group element. It
+ 	can be absolutely positioned on the slide by adding a
+ 	transform="translate(x,y)" attribute. Or it can be placed in
+ 	the vertical flow by wrapping it in a <div> block element.
+ 
+ Supported XHTML Elements: ul, li, div
+ <ul>
+ 	attributes:
+ 		font-size=(number) required, inherited
+ 		line-height=(number) required, inherited
+ 		bullet=('on'|'off') default: 'on'
+ <li>
+ 	attributes:
+ 		bullet=('on'|'off') default: 'on'
+ <div>
+ 	attributes:
+ 		font-size=(number) required, inherited
+ 		line-height=(number) required, inherited
+ 		height=(number) default: auto (calculated from font-size 
+ 						and line-height)
+ 		align=('left'|'center'|'right') default: 'left'
+ 	Text is wrapped by newline characters within a div.
+ 
+ Each ul and div needs a font-size and line-height specified. They can
+ be specified on any of the following elements: slides, slide, ul, div.
+ They are then inhereted and can be overriden (as shown in the above
+ example).
+ 
+ NOTE: Each ul and div MUST have a font-size and line-height attribute
+ defined, whether on self or inhereted. This is a common source of error.
