Bug 96750 – [BlackBerry] Prevent scroll adjustment of input fields when region of interest mechanism active

• Component: WebKit BlackBerry
• Status: RESOLVED FIXED

[Arvid Nilsson]

The region of interest mechanism replaces the scrolling/zooming functionality
in
BlackBerry::WebKit::InputHandler::ensureFocusTextElementVisible(CaretScrollType
scrollType).

We accomplish this by introducing a new fine-grained setting for the various adjustment modes.

Whoever enables ROI needs to disable all scroll types using the new setting.

I would name it scrollAdjustmentForInputFieldsPolicy, but this this also ok.

> Source/WebKit/blackberry/WebKitSupport/InputHandler.h:71
> +    enum CaretScrollType { CenterAlways = BlackBerry::Platform::Settings::ScrollAdjustmentCenterAlways,

> +                           EdgeIfNeeded = BlackBerry::Platform::Settings::ScrollAdjustmentEdgeIfNeeded };

there are compile asserts we can add to ensure these values match.
