2009-11-09(svn r18031) -Codechange: since basically r7157 adding up 'all' mouse ↵rubidium
movement isn't needed anymore because after each even that movement is handled and the counter is reset. As such simply assigning instead of adding works.
2009-10-17(svn r17787) -Codechange: be a bit more verbose about while allegro failed ↵rubidium
with some actions.
2009-10-15(svn r17776) -Codechange: [SDL] make "update the video card"-process ↵rubidium
asynchronious. Profiling with gprof etc. hasn't shown us that DrawSurfaceToScreen takes a significant amount of CPU; only using TIC/TOC it became apparant that it was a heavy CPU-cycle user or that it was waiting for something. The benefit of making this function asynchronious ranges from 2%-25% (real time) during fast forward on dual core/hyperthreading-enabled CPUs; 8bpp improvements are, in my test cases, significantly smaller than 32bpp improvements. On single core non-hyperthreading-enabled CPUs the extra locking/scheduling costs up to 1% extra realtime in fast forward. You can use -v sdl:no_threads to disable threading and undo this loss. During normal non-fast-forwarded games the benefit/costs are negligable except when the gameloop takes more than about 90% of the time of a tick. Note that allegro's performance does not improve with this system, likely due to their way of getting data to the video card. It is not implemented for the OS X/Windows video backends, unless (ofcourse) SDL is used there. Funny is that the performance of the 32bpp(-anim) blitter is, at least in some test cases, significantly faster (more than 10%) than the 8bpp(-optimized) blitter when looking at real time in fast forward on a dual core CPU; it was slower. The idea comes from a paper/report by Idar Borlaug and Knut Imar Hagen.
2009-10-14(svn r17773) -Cleanup: sdl.h isn't needed for allegrorubidium
2009-08-21(svn r17248) -Fix: add GPL license notice where appropriaterubidium
2009-06-30(svn r16700) -Fix: if allegro fails to start or fails open a window or sound ↵rubidium
card fall back to another driver
2009-06-27(svn r16677) -Codechange: Dimension width and height are unsigned.alberth
2009-06-01(svn r16491) -Codechange: Added parentheses around bitwise operators for ↵alberth
code style.
2009-05-06(svn r16242) -Codechange: rework pausingrubidium
-Fix [FS#2864]: autopause and manual pausing conflict with eachother -Fix: new game + pause on new game + autopause make the game not unpause on the first join
2009-01-19(svn r15156) -Fix: add scrollwheel support to allegrorubidium
2008-11-29(svn r14641) -Change [Allegro]: when making a debug build revert Allegro's ↵rubidium
hooks on SIGSEGV/SIGABRT so one can actually use gdb. -Change: make it more clear that Allegro's failing to find a driver.
2008-11-26(svn r14636) -Add: DOS port of OpenTTD, without network support though.rubidium
2008-11-25(svn r14632) -Add: support Allegro as midi backend.rubidium
2008-11-25(svn r14631) -Add: support for Allegro as sound backend.rubidium
2008-11-25(svn r14630) -Add: support Allegro as video backend.rubidium
