Tags: 0.9.20060529-1
* New upstream CVS snapshot.
* Update local cdbs snippet copyright-check.mk:
+ Broaden scan to also look for "(c)" by default.
+ Make egrep options configurable.
+ Ignore auto-tools files.
* Bump up standards-version to 3.7.2 (no changes needed).
* Let dh_strip do the stripping (not the make install target).
* Update local cdbs snippet copyright-check.mk:

* Ctrl-F5 = grab mouse (in windowed mode)
28
28
*
29
29
* FIXMEs and TODOs:
30
* - Windows requires an extra mouse event to update the actual cursor image?
30
31
* - Ctr-Tab for suspend/resume but how? SDL does not support that for non-Linux
31
32
* - Ctrl-Fn doesn't generate SDL_KEYDOWN events (SDL bug?)
32
33
* - Mouse acceleration, there is no API in SDL yet for that
33
34
* - Force relative mode in Grab mode even if SDL provides absolute coordinates?
34
* - Fullscreen mode
35
35
* - Gamma tables support is likely to be broken here
36
36
* - Events processing is bound to the general emulation thread as SDL requires
37
37
* to PumpEvents() within the same thread as the one that called SetVideoMode().
38
38
* Besides, there can't seem to be a way to call SetVideoMode() from a child thread.
39
* - Refresh performance is still slow. Use SDL_CreateRGBSurface()?
40
39
* - Backport hw cursor acceleration to Basilisk II?
41
40
* - Factor out code
