Viewing changes to src/SDL/video_sdl.cpp

Committer: Bazaar Package Importer
Author(s): Jonas Smedegaard
Date: 2005-07-30 20:42:20 UTC
mfrom: (1.1.1 upstream)
Revision ID: james.westby@ubuntu.com-20050730204220-1nl1cg2jkjvy63ry

Tags: 0.9.20050730-1

* New upstream CVS snapshot.
* Build-depend on virtual libsdl-dev (not libsdl1.2-dev).
* Invoke init rules also on clean (to separate better from official
builds).
* Update URL of upstream source in debian/copyright.

* NOTES:

* The Ctrl key works like a qualifier for special actions:

* Ctrl-Tab = suspend DGA mode (TODO)

* Ctrl-Esc = emergency quit

* Ctrl-F1 = mount floppy

* Ctrl-F5 = grab mouse (in windowed mode)

* FIXMEs and TODOs:

* - Ctr-Tab for suspend/resume but how? SDL does not support that for non-Linux

* - Ctrl-Fn doesn't generate SDL_KEYDOWN events (SDL bug?)

* - Mouse acceleration, there is no API in SDL yet for that

* - Force relative mode in Grab mode even if SDL provides absolute coordinates?

* - Fullscreen mode

* - Gamma tables support is likely to be broken here

* - Events processing is bound to the general emulation thread as SDL requires

* to PumpEvents() within the same thread as the one that called SetVideoMode().

* Besides, there can't seem to be a way to call SetVideoMode() from a child thread.

* - Refresh performance is still slow. Use SDL_CreateRGBSurface()?

* - Backport hw cursor acceleration to Basilisk II?

* - Factor out code
