only-visible option does not work

[KaiMartin]

The "only-visible" check box does not seem to change anything in pcb. This affects the PNG and EPS export. The bug shows in current git head and in version 20110918. To reproduce:

1) Open a layout

2) Zoom in to show only part of the layout on screen

3) File -> Export_Layout -> png

4) check the only-visible check box

5) click OK
The resulting PNG file shows the whole layout rather than the clip defined by the current view.

The exporters do not have any way to tell what the "current view" is. What "only-visible" means is to limit the bounds of the PNG to the items that are currently "visible" (i.e. enabled layers/pins/vias/rats) on the board, not on the screen. I.e. it does the equivalent of "autocrop" would in a paint program.

Ok , then the caption of the flag should say so. E.g,

   [x ] only visible layers

I'll prepare a patch, that chanmges just that.

In addition, I'll file a feature request for a way to export just a portion of the layout. This would be handy in a number of situations. Documentation, communication of a specific area, zoom-print of details, etc. The area may be given by the current view. But other ways would also do. IMHO, the most simple would be a numeric enty of two coordinates that give corners of the print window.
