annotate Framework/Oracle/GetOrthancImageCommand.cpp @ 956:a7351ad54960
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)
