Subject: Add const to getViewerPose()
X-Git-Tag: accepted/tizen/6.0/unified/20201030.111113~472^2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d7cbe6e947ed894ed61dddcc3cf0804982b4e3b8;p=platform%2Fupstream%2Fopencv.git

Add const to getViewerPose()

getViewerPose() doesn't modify an object of the class so it can be
made const. It also makes this method consistent with other getters
in the class as they are defined as const.
