The actual javascript names are common for all maps with same
provider, so you should only define the icons for each map provider
once.Defining an icon requires that the following be defined for each icon type name:
icon_size(+Name, X, Y)
size of icon imageshadow_size(+Name, X, Y)
size of shadow imageicon_anchor(+Name, X, Y)
offset from UL of image to the point
touching the spot on the mapshadow_anchor(+Name, X, Y)
offset
from UL of shadow image to the point touching the spot on mappopup_anchor(+Name, X, Y)
offset from the point touching map to
where the popup appears (so, eg, Y coord is often negative)
