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