ALL: cursor pulsates too slow

Description

ScummVM 0.4.2cvs
Built on Jun 19 2003 11:18:43
With the original interpreters the cursor pulsates
faster. I compared it with the C64, Amiga and PC
versions of Scumm games. On all those systems, the
pulsating is about twice that fast.
I think the faster pulsating looks nicer and should be
done that way in ScummVM, too. Beside this, it would be
closer to the original anyways.

Note that with PC games the cursor flickers a bit with
the original interpreters, which I think is not
supposed to be that way and there is no need to do that
flickering in ScummVM, just the faster pulsating would
be nice.

If you want to check this out, and the flickering on
your PC is too much to even recognise the actual
pulsating, just try some games on C64 and Amiga! Or
also try it with monkeyvga on PC where there is much
less flickering in pause mode.

I think this was from the beginning on since the cursor
works flawless otherwise.

Doubling the speed would be easy. Just change the two lines
in animateCursor() in gfx.cpp that currently are:

if (!(_cursor.animateIndex & 0x3)) {
decompressDefaultCursor((_cursor.animateIndex >>
2) & 3);

to

if (!(_cursor.animateIndex & 1)) {
decompressDefaultCursor((_cursor.animateIndex >>
1) & 3);

I have no idea whether or not this is the correct speed though.

I get the 'proper' cursor speed (compared to the Amiga
interpreters) by removing the 'slowdown' altogether. That is,
simply doing "decompressDefaultCursor(_cursor.animateIndex
& 3);" and dropping the 'if (!(_cursor.animateIndex &
whatever))' check seems to get the cursor to flash at the
proper speed.
It's possible the Amiga interpreters flash the cursor more
quickly than the PC versions, though...

I doubled the cursor animation speed as per erik's suggestion, and
also did something similar for the GUI cursor. Is that better?
