Bug 147137 – [CoordinatedGraphics] Remove unnecessary two virtual methods from TiledBackingStoreClient

• Component: WebKit EFL
• Status: RESOLVED FIXED

[Ryuan Choi]

tiledBackingStoreContentsRect() and tiledBackingStoreVisibleRect() are ambiguous methods to get contentsRect and visibleRect from CoordinatedGraphicsLayer.
CoordinatedGraphicsLayer can pass them directly if needed.

Any reason you didn't submit to EWS ?

Sorry for the late answer.

When we don't adjust mapFromContents(), is there any problem ?

mapFromContents() applies a content scale factor.

IntRect TiledBackingStore::mapFromContents(const IntRect& rect) const
{
    return enclosingIntRect(FloatRect(rect.x() * m_contentsScale,
        rect.y() * m_contentsScale,
        rect.width() * m_contentsScale,
        rect.height() * m_contentsScale));
}

With this patch, coverageRatio will get dirtyRect which is already scaled, while previous coverageRatio get contentsRect.

I will rename these as scaledXXX not to confuse.

I can't find behavior change here. So rs=me that there is no behavior change on the assumption. However someone(yoon?) might want to take a final look before landing.
