Thanks!, I did check it out and I think simply adding the new render modes to the render mode

list should be sufficient. The first line (`{ FT_LOAD_NO_BITMAP | FT_LOAD_TARGET_NORMAL, FT_RENDER_MODE_SDF }`)

is to use the `sdf` module for rendering and the second (`{ FT_LOAD_RENDER | FT_LOAD_TARGET_NORMAL, FT_RENDER_MODE_SDF }`)

is to invoke the `bsdf` module since it requires bitmap input. Please check it out, if there are other

things required please let me know, I'm attaching the diff below.
