Bug#515597: When windowed and without focus, it bounces the cursor around

[Sylvain Beucler]

Hi Enrico,

(I just figured that I wasn't subscribed to freedink's BTS (nor to
pkg-games-devel), and so I discovered freedink's first Debian bug
today :))

Alt + Enter does the trick.
That's what I try first, as it's what ms woe games often use.
What did you try?

Note that it's grabbed only on the title screen, where the mouse is
active.

Possibly this part can be improved, but the goal is to prevent the
mouse from going off of the screen.

For example, when you click on "Continue", you get a list of
savegames. Mouving the mouse up and down cycles through the savegames,
and when it's at the bottom, going down some more goes back to the
first entry in a loop.

When the mouse isn't grabbed, the mouse may go off of the screen while
the game pointer is in the middle of the savegames list, which is
frustrating.

This part is essentially using *relative mouse* moves rather than
*absolute positionning*, which justifies grabbing the mouse.

Since SDL doesn't provide a way to grab the mouse as the original DX
version did, FreeDink simulates this by recentering the mouse
continuously (when the game has focus). Which explains that when your
mouse goes over FreeDink while it's a partially masked window, the
mouse pointer is moved to the center of the FreeDink window
nonetheless.

SDL has a solution for fullscreen mode, where you get relative moves
events even when the mouse is stuck one edge of the screen. Sadly this
can't work in windowed mode where the games just loses focus.

Again this only happens in the title screen, or in D-Mods where the
mouse is kept active. I don't have this problem as soon as I start or
continue a game.  I'm open to alternatives though :)
