Some graphic line thickness were initialized to 0.
The actual line thickness is set after reading config.
But in some cases the config does not exist, and 0 line thickness creates draw issues.
Please note that the symbol cache is not embedded in the schematic file
to allow for round robin testing with the existing file format. Once
the parser round robin testing is complete, the symbol cache will be
embedded in the schematic file.
This implements all existing symbol library object support and the ability
to save and load symbol library files between file formats for round robin
testing.
