示例1: GrAssert

bool GrRectanizerPow2::addRect(int width, int height, GrIPoint16* loc) {
    if ((unsigned)width > (unsigned)this->width() ||
        (unsigned)height > (unsigned)this->height()) {
        return false;
    }

    int32_t area = width * height;

    /*
        We use bsearch, but there may be more than one row with the same height,
        so we actually search for height-1, which can only be a pow2 itself if
        height == 2. Thus we set a minimum height.
     */
    height = GrNextPow2(height);
    if (height < MIN_HEIGHT_POW2) {
        height = MIN_HEIGHT_POW2;
    }

    Row* row = &fRows[HeightToRowIndex(height)];
    GrAssert(row->fRowHeight == 0 || row->fRowHeight == height);

    if (0 == row->fRowHeight) {
        if (!this->canAddStrip(height)) {
            return false;

            }
            // that row is now "full", so retarget our Row record for
            // another one
