Usage

- ``height`` Font size. 
- ``path_cb`` A function to get the image path of a character. 
  Return ``NULL`` if no image should be shown, but the character itself.
- ``user_data`` Pointer to user data.

To use the *imgfont* in a label, reference it:
:cpp:expr:`lv_obj_set_style_text_font(label, imgfont, LV_PART_MAIN)`
