Text colors extracted with bp() are fully opaque

A recent update has caused a bug where text colors extracted from a bitmap using bp() to always be fully opaque. For example, using bp(lmutedtc, gv(mainbg)) used to return semi-transparent black or white: #99000000 or #99FFFFFF. Now they only return fully opaque black or white. This occurs on Samsung Galaxy S8 and Samsung Note 10+.
