MadButterfly: src/paint.c annotate

annotate src/paint.c @ 425:09a66063b25d

Fix issue of missed function for unittest. If we make for unittest, it will be failed for missed functions. Since we change name of functions to avoid type conflict, ld can not find the functions with original names. So, we make dummy functions to resolve it. We had better decouple them to avoid this problem.
