What steps will reproduce the problem?
1. Create an SVG file in GIMP, which by default uses inches for width and 
height attributes of SVG.
2. Try to load the file using the library.
3. You'll get a stack with exceptions, something like this:

What is the expected output? What do you see instead?
The SVG-file should be displayed.

What version of the product are you using? On what operating system?
The latest 1.1.

Please provide any additional information below.
The problem is in line 601 of SVGParser which processes only "px" suffix of 
attributes, whereas a file may contain "in" as well. Currently, if an attribute 
is specified as, for example, "200in", the library passes the value as is for 
float parsing, which is incorrect float, of course.

Same issue with "mm" as size.
