[Xastir] Slow raster map render

[Tom Hayward]

Why is Xastir slow to render raster maps? I'm curious what is actually
happening behind the scenes. It appears that Xastir is re-projecting
the raster maps, requiring an expensive render. Why not just
re-project the APRS stations and any shapefile overlay to match the
raster tiles? Wouldn't this be much faster?

I normally use Xastir with a USGS topo tiles base layer (from ESRI,
using the OSM tile loader) with an OSM Cloudmade shapefile overlay.
