FreeRDP/include/freerdp/server/shadow.h
akallabeth 9268cee35e [server,shadow] shadow_subsystem_pointer_convert_alpha_pointer_data 
the function uses implicit color formats. Replace this with the function
shadow_subsystem_pointer_convert_alpha_pointer_data_to_format with
explicit source color format.
Deprecate the old function.
