* Abstract all instances of NewMinList as it causes alert 80000006 on OS3Chris Young2015-08-051-1/+1
|
* Scale cached favicons before they are cached. This avoids the need to scale ↵Chris Young2015-06-221-0/+8
| | | | icons on menu creation.
* Remove the overwrite check in bitmap_save as it causes duplicate overwrite ↵Chris Young2015-06-221-4/+0

* Attempt to fix spurious plotter crashesChris Young2015-04-271-1/+8

* Remove bogus commentChris Young2015-04-251-2/+0
|
* As the content interface is now doing the scaling, we render to a native ↵Chris Young2015-04-251-51/+44
| | | | | | BitMap and then copy that to the RGBA32 bitmap buffer without re-scaling. The native BitMap is currently discarded and will be re-created when it is displayed.

* Abstract p96WPA, although it still needs P96 currentlyChris Young2015-01-201-12/+2
|
* Abstract P96 functions away so we can decide what to use at run-time.Chris Young2015-01-201-7/+9
| | | | This allows us to avoid opening P96 on OS4.1FE in future, and not require it to be installed on OS3.
