Clip singleTile image to maxExtent
Override getImageSize function to take clipped images into account

singleTile layers may have clipped images to not exceed the maxExtent.
Whitespace fixes
Use correct getImageSize API

Without the bounds argument, getImageSize would fail in singleTile mode.
Updating tests and adding a test to make sure that clipping works
Changed documentation of OpenLayers.Bounds.toBBOX from Significant Figures to Decimal Places as this is what the method actually does.
ZoomBox sprite positions not defined for EditingToolbar

.olEditingToolbar class was not assigned to the olControlZoomBoxItem classes, which resulted in incorrect buttons.

Correct handling of 0 and Infinity in Min/MaxScaleDenominator

minScale and maxScale values of 0 and Infinity do not make sense in
OpenLayers, but they are used in WMS GetCapabilities 1.3.0. to indicate
that there is no minScale or maxScale restriction. Assuming that the
capability values for minScale and maxScale are passed as config options
to a WMS layer, it is better to not set minScale and maxScale when 0 is
found in MinScaleDenominator or Infinity is found in MaxScaleDenominator.

Making tile scaling work with the Zoomify layer

Because zoomify tiles have different sizes, we also need to store the
standard tile size on the backbuffer. The Zoomify layer gets an override
for the createBackBuffer method to make sure that the native image size
is used.
