Automate the running of Lancelot visual test suite from QT3DS-103 on both runtime 1.x and runtime 2.x so that we can get comparison of visual results from both. The test setup needs to:

• Compare render results of new 1.x engine changes against old baseline to stop regressions.
• Compare render results of new 2.x engine changes against old baseline to stop regressions.
• Compare render results between latest 1.x and 2.x engines to get visibility to rendering quality changes between the two.
