Fixes possible concurrency issue - makes code usable in a multithreaded environment. imageReleasCb releases imageContainer after bgfx::createTexture...() is called. If bgfx::frame() is called from another thread, the release can happen before imageContainer is used in bgfx::calcTextureSize(), leading to a crash. Although loadTexture() is not used in multithreaded environment in the examples, calling bgfx::calcTextureSize() before bgfx::createTexture...() is a better reference for users.
