/* Graphical Luna / Felix animation
   Frames are 4x3 on OLED and oriented for OLED_ROTATION_270.

   Modified from @HellSingCoder's Luna dog
   (https://github.com/HellSingCoder/qmk_firmware/tree/master/keyboards/sofle/keymaps/helltm)

   Includes white Felix dog frames from @ItsWaffIe
   (https://github.com/ItsWaffIe/waffle_corne/blob/proton-c/firmware/oled.c)


   Usage guide
   1 Place this file next to keymap.c or in userspace.
   2 Add the following lines into rules.mk:
        OLED_ENABLE = yes
        SRC += oled-luna.c
   3 Animation defaults to Luna, an outlined dog. Add
     'OPT_DEFS += -DFELIX' into rules.mk for "filled" version.
   4 The 'oled_task_user()' calls 'render_mod_status()' from "oled-icons.c"
     for secondary OLED. Review that file for usage guide or replace
     'render_mod_status()' with your own function.
