Detailed Description

class for drawing the outlines of the preview canvas and the crop rectangle in the overview openl scenes it also creates meshes that are used to darken the outside regions it works similarly to the mesh remapper used for the images, with the exception that instead of remapping from image to projection, this needs to remap from projection to another projection

it has two modes of operation:

• Subdivide the mesh recursively until a mesh with desired resolution is obtained. * This is very good in most of the cases except where the canvas also covers some regions not in the panorama * This corresponds to the vertex coord remapper
• Subdivide the mesh certain amount of times in all directions * This corresponds to the tex coord remapper
