Made IsContextLost automatically set the flag by checking with the emscripten WebGL wrapper + added a LOT of logging messages right before throwing ErrorCode_BadSequenceOfCalls exceptions + increased the http request timeouts from 60 to 600 sec (big datasets in some recent customer use cases) + added IsContext lost through the Viewport/Context layer (to make it reachable from external API) + the same for the underlying device context (for debug)
