Cleanup temporary setting of image interpolation quality in GraphicsContext::drawImage*

[zalan]

This is highly error prone with all the copy-paste code in GraphicsContext::drawImage, GraphicsContext::drawTiledImage, GraphicsContext::drawImageBuffer.

if (useLowQualityScale) {
       InterpolationQuality previousInterpolationQuality = imageInterpolationQuality();
       setImageInterpolationQuality(InterpolationNone);
       image->draw(this, styleColorSpace, dest, src, op, blendMode, useLowQualityScale);
       setImageInterpolationQuality(previousInterpolationQuality);
   } else
       image->draw(this, styleColorSpace, dest, src, op, blendMode, useLowQualityScale);

OK

Should use a reference instead of a pointer.

> +    InterpolationQuality m_newInterpolationQuality;

Could just store a m_currentInterpolationQuality != m_newInterpolationQuality boolean instead.

Good point! I'll do that.
