virtual bool CanCreateTextureCurrentThread() const;
CanCreateTextureCurrentThread reports whether textures can be created on the current thread. Normally this is only false if using a multi-threaded renderer, and the platform requires that textures be created on the render thread (default implementation). If a platform does not have these restrictions, it could simply return true from this method.
Returns true if the current thread has access to create a texture, false otherwise.
