GdalTools: unclear results from clipping

Description

Currently, when >1 layer is loaded into the canvas, clipping results are difficult to interpret. The tool attempts to clip all the loaded layers, whereas I guess the user expects only the topmost layer will be clipped.

All the active layers (visible ones) are clipped. When more then one layer are active the result is the merge of all the active layers clipped by the extent.

In this moment there's an issue because the topmost layer is inserted as the first one in the gdal_merge command, but seeing at the ​gdal_merge manpages, "In areas of overlap, the last image will be copied over earlier ones".

So when there are > 1 layers active, in the result the last layer in the TOC is over the topmost one. I'm going to fix it as soon as possible.

Fixed in r15125. I guess I can close this ticket.
