+ Mismatch between the system buffer size the browser side renders audio at

+ and the buffer size it requests from renderer. When equals zero, it means

+ renderer buffer size is a multiply of system buffer size, and render calls

+ from browser to renderer are issued evenly. When -1, it means the renderer

+ buffer sizes is larger than system buffer size, but is not an exact multiply

+ of it; in this case browser periodically skips a call to renderer. When

+ positive, floor(value/2) reflects the number of extra consecutive render

+ requests issued by browser to renderer each time to fulfill the system audio

+ render request; if (value/2) is not integer, then plus one more extra call

+ is issued periodically.
