[Qgis-developer] Proposal - Change mIconProjectionEnable/Disable Icons

[Alexandre Neto]

This is the commit with the proposed changes.

It has the new Icons and different behavior of the CRS text. I.e:

When OFT is enable, it will show only the EPSG:<code>
When OTF is disable, it will show EPSG:<code> (OTF off)), besides the icon
is crossed.

Note: I did not change the default settings to make OTF enabled by default.
