ImageButton() is flawed as 'id' is always derived from 'texture_id' (see #2464 #1390) We provide this internal helper to write your own variant while

Note: p_data, p_step, p_step_fast are _pointers_ to a memory address holding the data. For an Input widget, p_step and p_step_fast are optional. Read
