0030978: Visualization - stack-use-after-scope reported by Clang address sanitizer in OpenGl_Text.cxx

Browse Source 
Implementation of auxiliary class in OpenGl_Text.cxx is corrected to avoid storing reference to temporary object.

Off-topic: test parse rules are corrected to recognize situation when test is killed by elapsed time, and report it as such.
