+=item resize_image()
+
+ Get correct sizing parameter for an image given
+ it's initial ht. and wid. This allows sizing of
+ images that are generated on-the-fly (e.g. gnuplot)
+ as well as serving as a utility for image_size.
+
+ Parameter:
+ height_param
+ width_param - Initial picture dimensions.
+ scaling - A scale factor.
+ parstack, - the current stack of tag attributes
+ from the xml parser
+ safeeval, - pointer to the safespace
+ depth, - from what level in the stack to look for attributes
+ (assumes -1 if unspecified)
+ cis - look for attrubutes case insensitively
+ (assumes false)
+
+ Returns:
+ height, width - new dimensions.

+
+ Converts a measurement in to mm from any of
+ the other valid LaTeX units of measure.
+ If the units of measure are missing from the
+ parameter, it is assumed to be in and returned
+ with mm units of measure
+
+=item LATEX_length()
+
+=item align_latex_image()
+
+ Wrap image 'stuff' inside of the LaTeX required to implement
+ alignment:
+ align_tex_image(align, latex_rendering, image)
+ Where:
+ align - The HTML alignment specification.
+ latex_rendering - rendering hint for latex.
+ image - The LaTeX needed to insert the image itsef.
+ width,height - dimensions of the image.
+ Returns:
+ The 1/2 wrapped image and the stuff required to close the
+ wrappage. This allows e.g. randomlabel to insert more stuff
+ into the closure.
+
+
+=item is_inside_of($tagstack, $tag)
+ This sub returns true if the current state of Xml processing is inside of the tag.
+ Parameters:
+ tagstack - The tagstack from the parser.
+ tag - The tag (without the <>'s.).
+ Sample usage:
+ if (is_inside_of($tagstack "table")) {
+ I'm in a table....
