SkPDF: treat alpha as color component.
Before this change, we converted the paint's alpha from a float to a
byte, then serialized it as a float in the range 0-1, with
full single-precision precision (~8 decimals). This was stupid.
Now, we store a float, and then serialize it with 4 decimals of
precision, like other color components.
