Bug 130962 – [CoordinatedGraphics] Content scale factor should not be applied to draw contents when fixed layout is not used.

• Status: RESOLVED
• Resolution: FIXED
• Component: WebKit2

[Eunmi Lee]

Contents is painted by applying current page scale factor in the coordinated graphics even though page scale factor is already applied to the contents when fixed layout is not used.
That means page scale factor is applied twice when fixed layout is not used.

We can see wrong scaling results in the efl port's MiniBrowser using control+"-/+" button.
- Bottom of the screen is not rendered (just white) when scale factor is less than 1.0.
- We can not scroll down to the bottom of the page when scale factor is greater than 1.0.

If fixed layout is not used delegating scaling is also not used,
so we should not apply page scale factor to draw contents in that case.

I'm not coordinated graphics expert though, as far as I know, Coordinated graphics is only used by EFL port. So, rs=me for EFL port development.
