The main areas of work for bringing Ngale into the 2nd decade of the 21st century --- i.e., running native on Intel processors -- seem to be (these are not necessarily discrete chunks of work):

• Music drawing
• Operating system
• resource file (bundle) elimination
• User interface (these last two imply redesigning graphics bitmaps for icons, etc.)
• clean up all unreached/uncompiled code

• Required: MacOS Snow Leopard, Lion, and Mountain Lion (10.6 - 10.8), Intel only (32 or 64 bit)
• Desirable: iPad, iOS ?? (Yes, we should leave the door open for ARM/iOS -chirgwin)

• Skip Lion (10.7) and go straight to Mountain Lion (v10.8) (with backwards down to 10.6)

• Briard is the only officially and fully supported notation font. Rationale: intellectual property issues with Sonata; BlueNotz is less appropriate for most users we care about (e.g., us :-) )
• Support for other notation fonts -- at least Sonata and BlueNotz -- is desirable

• Xcode. Initially, 4.2 is preferred; 3.2 should be okay too, though projects probably aren't backwards compatible (are they?)

Quartz 2D

• This should be broken down into finer granularity/detail and github issues opened
• Strategy: add functionality to Geoff's Cocoa proof-of-concept (instead of the original "Move away from MacOS 10.4 SDK / Carbon / Rosetta towards MacOS 10.8 / Cocoa")
• Avoid deprecation warnings.
• Build automated testing framework.
• Use property list (PList, or other plain text file) and bitmap image files instead of resources (.rsrc).

Graphics toolkit (C++, cross-platform, 3rd party)

• Candidates: Cairo, QT, GTK, JUCE, emd; others?
