Updated code for cell size calculation

* Cairo version: 1.16.0-1
* SVG output doens't seem as broken as before with the current cairo version
* Transparency doesn't work. Transparent layers aren't rendered at all.

-# GDS-Render
-
-This software is a rendering programm for GDS2 layout files.
-The GDS2 format is mainly used in integrated circuit development.
-This program allows the conversion of a GDS file to a vector graphics file.
-
-## Output Formats
-* Export GDS Layout to LaTeX (using TikZ).
-* Export to PDF (Cairographics).
-
-# Features
-Note: Due to various size limitations of both TikZ and the PDF export, the layout might not render correctly. In this case adjust the scale value. A higher scale value scales down your design.
-
-* Configurable layer stack-up.
-* Layer colors configurable as ARGB color values.
-* Command line interface.
-* ~~Awesome~~ Somehow usable GUI.
-
-# License and Other Stuff
-* Free software (GPLv2 _only_)
-* Coded in plain C using GTK+3.0, Glib2, and Cairographics
