ocornut 2bf6552f2f Fonts: Fixed/improved support for legacy backend. SetTexID() writes into our ImTextureData to keep the indirection, clear TexIsBuilt. 
The idea is that a legacy backend can somehow add a if (!atlas->IsBuilt()) ImGui_ImplXXXXX_CreateFontsTexture() call _after_ Render() and some features are supported.
