On some Macs there is an AMD driver bug that requires each vertex attribute to
be 4 byte aligned. This breaks our per-vertex coverage attribute. We were using
4 bytes of space for the coverage attribute but setup GL to read just the high
byte. With this change we'll read the low byte which is aligned. The comments
now say the caller is required to set all four channels to the same value.
