Bug 121180 – [Windows] Avoid converting from IntSize->SIZE->IntSize

• Component: WebKit Misc.
• Status: RESOLVED FIXED

[Brent Fulgham]

There are several code paths where a WebKit IntSize is converted to a Microsoft SIZE struct, only to be changed back to an IntSize for further work.

Instead, revise the API to take an IntSize argument so we don't have to do this wasted conversion. The only counter-case is in the IconDatabase, where we will have to convert a SIZE to an IntSize to accommodate this change. However, this "extra copy" code path is much less frequent than the other cases, which are used for cursor handling and the copy/paste buffer.

I think this should take a const IntSize.

Ditto. And use override.

I can't. The argument is optional, and the implementations take different code paths if an argument is supplied.

Ditto for me, too. But I will change to use the OVERRIDE macro.
