[mkgmap-dev] Border of polygon

Hi Karl

You could simply not match it in "polygons" but render the lines that define it.

Alternatively, what I do, is catch it early in "polygons" to render it but with
[... continue] and render it striped/transparent with a high _drawOrder.

[_polygon]
Type=0x16
String=Nature Reserve
Xpm="32 32 2 1"
    "\ c #00FF00"
    "  c none"
    "\\\\\\        \\\\\\\\        \\"
    "\\\\\\\        \\\\\\\\        \"
    "\\\\\\\\        \\\\\\\\        "
    " \\\\\\\\        \\\\\\\\       "
    "  \\\\\\\\        \\\\\\\\      "
    "   \\\\\\\\        \\\\\\\\     "
    "    \\\\\\\\        \\\\\\\\    "
    "     \\\\\\\\        \\\\\\\\   "
    "      \\\\\\\\        \\\\\\\\  "
    "       \\\\\\\\        \\\\\\\\ "
    "        \\\\\\\\        \\\\\\\\"
    "\        \\\\\\\\        \\\\\\\"
    "\\        \\\\\\\\        \\\\\\"
    "\\\        \\\\\\\\        \\\\\"
    "\\\\        \\\\\\\\        \\\\"
    "\\\\\        \\\\\\\\        \\\"
    "\\\\\\        \\\\\\\\        \\"
    "\\\\\\\        \\\\\\\\        \"
    "\\\\\\\\        \\\\\\\\        "
    " \\\\\\\\        \\\\\\\\       "
    "  \\\\\\\\        \\\\\\\\      "
    "   \\\\\\\\        \\\\\\\\     "
    "    \\\\\\\\        \\\\\\\\    "
    "     \\\\\\\\        \\\\\\\\   "
    "      \\\\\\\\        \\\\\\\\  "
    "       \\\\\\\\        \\\\\\\\ "
    "        \\\\\\\\        \\\\\\\\"
    "\        \\\\\\\\        \\\\\\\"
    "\\        \\\\\\\\        \\\\\\"
    "\\\        \\\\\\\\        \\\\\"
    "\\\\        \\\\\\\\        \\\\"
    "\\\\\        \\\\\\\\        \\\"
;   "12345678901234567890123456789012"
[end]

I do the same for danger_area, but in red and the stripes going the other way!
