WM_STYLECHANG{ING/ED}

[Dimitrie O. Paun]

Hi folks,

In my relentless quest for speed :), I discovered that we don't send
a WM_STYLECHANGED message when we flip the WS_VISIBLE, or WS_VSCROLL,
and maybe a bunch of others, I haven't checked.

Shouldn't we send such a message, when we touch *any* WS_[EX_]* bits?

Sometimes yes, sometimes no. The only way to know is to test that
specific situation under Windows.

[Note to self: I should find a way to test stuff on Windows]

So my question to you: do you know for sure of any case when we change
some of those bits, and we should not emit a notification?

No, I haven't looked into it. That doesn't mean we should start
sending notifications everywhere without checking what Windows does...
