Description

The class Tiling (in org.gvsig.destkop/org.gvsig.desktop.compat.cdc/org.gvsig.fmap.mapcontext/org.gvsig.fmap.mapcontext.api/src/main/java/org/gvsig/fmap/mapcontext/layers/) does not correctly compute the viewport for tiles, in method getTileViewPort().

The Viewport is cloned from the parent, then assigned the tile parameters (height, width and envelope) and then it gets assigned the affine transform from the parent viewport. This is incorrect as the new viewport automatically computes its own affine transform, which is different from the parent. Instead of assigning the parent affine transform, the new viewport has to be assigned the offset of the tile, in this way the affine transform is correctly (internally) calculated by the viewport itself.

I attach a patch that solves the problem.

This error causes the WMSs to don't get correctly printed (some tiles are missing). See related bug.
