`YGRoundValueToPixelGrid` currently rounds negative numbers incorrectly. For example: ``` YGRoundValueToPixelGrid(-2.2, 1.0, /* ceil */ false, /* floor */ true) = -2.0 ``` However, that operation is supposed to take the floor of the number so the result should acutally be `-3.0`. There's a detailed comment in `YGRoundValueToPixelGrid` about the fix and why it works. A symptom that manifested because of this bug is that text nodes could get smaller and smaller on each layout pass. For details see facebook#824. Fixes facebook#824 Adam Comella Microsoft Corp.
