+ 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)
