Adds static maps

[darthmaim]

DO NOT MERGE YET - WORK IN PROGRESS

This adds static maps (render a part of the GW2 map to an image) to gw2tools.

TODO

• Tests
• Render labels over icons
• Render custom elements
  • Icons (for example WvW objectives)
  • Images (for example circles for event regions)
  • Labels (for example bigger/colored to highlight a point of interest)
  • Polylines (for example region outlines/event locations)
• PointsOfInterests with lower opacity (for example waypoints in a different floor)
• Prevent overlapping labels (?)
• Usage examples
• Docs

Basic Usage

// setup map
$map = new StaticMap($continent, $floor);
$map->setBounds($continent_rect[0], $continent_rect[1]);

// add pois that should be rendered
$map->addWaypoint($poiPosition, $poiLabel);

// render to an image
$image = $map->render(1024, 1024);

Here are two examples (code for these not released yet):

Lions arch, rendered with all waypoints, landmarks, vistas, …

The event Defeat the renegade charr. and the nearest nearest 3 points of interest. The red circle is the radius in which the event is active.
