Talk:Canvas Map API

Optimizations

• updating overhead: use smart symbols [1] and range-aware layers, emulate delta queries and use split-frame loops to update invisible layers in the background [2]
• symbol overhead:emulate instancing support by using a separate canvas as the cache for common symbols, and them re-use raster images via embedded canvas and texture maps instead, should reduce updating overhead significantly and should not require C++ changes, just fancy Nasal scripting [3]

TODO

• Port Stuart's F4 radar to use the MAP API: https://gitorious.org/fg/fgdata/blobs/master/Aircraft/a4/Nasal/radar.nas
