[ka-Map-users] Same API, but map images instead of tiles

That's what I'm trying to do. I want to be able to
display/hide vector layers listed in the legend
without creating all the tiles for the vectors. I
created a drawing canvas that retrieves the
vector-only layers whenever the map extent is changed.
The advantage I see is that I only have to create
tiles for my raster background. I can then draw all
the vector layers separately and return them in one
gif/png. Plus I can get images from a WMS as well.
It looks like it can be done without adding too much
sense to separate the raster and vector layers?
