Merge "Fix bound rectangle calculation in SkiaCanvasProxy::onDrawPosText"

    // by Minikin then it had already computed these bounds.  Unfortunately,

    // there is no way to capture those bounds as part of the Skia drawPosText

    // API so we need to do that computation again here.

    SkRect bounds;

    SkRect bounds = SkRect::MakeEmpty();

    for (int i = 0; i < glyphs.count; i++) {

        SkRect glyphBounds;

        SkRect glyphBounds = SkRect::MakeEmpty();

        glyphs.paint.measureText(&glyphs.glyphIDs[i], sizeof(uint16_t), &glyphBounds);

        glyphBounds.offset(pos[i].fX, pos[i].fY);

        bounds.join(glyphBounds);
