#179 BaseRenderer.CalculateTextWidth does not handle ArgumentException from MeasureText

[Thracx]

TextRenderer.MeasureText can throw an (undocumented) ArgumentException in certain conditions.

Adding a try..catch to BaseRenderer.CalculateTextWidth in Renderers .cs should fix the issue.

Exception StackTrace:
ArgumentException: Parameter is not valid.
