There are no text rendering functions in libyuv.

Its a bit problematic, rendering onto YUV 420 surfaces, due to subsampling on the chroma.

Good text rendering is quite hard to do well.  Antialiasing, kerning etc.

If its just for debugging purposes, we could consider a rudimentary 8x8 fixed font?
