The following behaviour manifests itself when adding a WMTS layer to a blank 
QGIS project.

When you add any WMTS layer and zoom to extent, what it actually does is zoom 
to the TileMatrixSet extent and not the layer. The layer is correctly 
advertising the WGS84BoundingBox but QGIS is ignoring it. If it used this value 
instead, zooming to layer for WMTS would make a lot more sense.

<Layer>
<ows:Title>Surat_Basin_Area.ecw</ows:Title>
<ows:Identifier>P1_Surat_Basin_Area.ecw </ows:Identifier>
<ows:WGS84BoundingBox>
<ows:LowerCorner>150.045708962027 -26.693037874264</ows:LowerCorner>
<ows:UpperCorner>150.447045150312 -26.243579854007</ows:UpperCorner>
</ows:WGS84BoundingBox>

So when you add, say, a layer in googlemapscompatible or globalcrs84pixel it 
will request the root tile index of the global tilematrixset, which for 
localized imagery will mean the dataset is rendered at the sub-pixel level (not 
shown!)

Is it possible to get QGIS to use the WGS84BoundingBox values?
