[Bug 635026] Re: Okular Trim margins doesn't work if paper colour is changed

[Lauri Lyly]

I confirmed this is the case, so ... there's this function "isWhite" in
utils.cpp which isn't used anywhere else than in
Utils::imageBoundingBox.

I modified it from

inline static bool isWhite( QRgb argb ) {
    return ( argb & 0xFFFFFF ) == 0xFFFFFF; // ignore alpha
}


to

inline static bool isPaperColor( QRgb argb ) {
    return (argb & 0xFFFFFF) == (Settings::paperColor().rgb() & 0xFFFFFF);
}

(obviously had to include "settings.h")

and now it works.
