1. 

2. Fix to usage of [Compressonator](https://gpuopen.com/compressonator/) on Linux: detect also lowercase `compressonatorcli` executable, following new Compressonator file naming in Linux.

3. Fix to usage of [PVRTexTool](https://developer.imaginationtech.com/pvrtextool/). We adjusted compression format names to follow latest naming from [PVRTexTool Command Line Options](https://docs.imgtec.com/oxy_ex-2/UtilitiesSrc/PVRTexTool/Documentation/PVRTexTool_Manual/topics/PVRTexTool%20CLI/command_line_options.html).

4. [GameAnalytics SDK usage](https://github.com/castle-engine/castle-engine/blob/master/tools/build-tool/data/android/integrated-services/game_analytics/README.adoc) on Android upgraded to 6.2.6.
