Subject: gallium/util: use ui[4] instead of ui in union util_color
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=fa4082320acaf0a1a22ae56144eef94b2997818d;p=mesa.git

gallium/util: use ui[4] instead of ui in union util_color

util_color often merely represents a collection of bytes, however it is
inconvenient if those bytes can only be accessed as floats/doubles for int
formats exceeding 32bits.
(Note that since rgba8 formats use one uint, not 4 bytes, hence the byte and
short member were left as is.)
