- remove method names from QgsDebugMsg calls as they are already included in the output - replace filename with file name in strings and comments instead of fileName (same for layerName) - fix debugging output in interpolation plugin (QgsDebugMsg migration ate the last argument where std::flush was used) - fix some common typos git-svn-id: http://svn.osgeo.org/qgis/trunk/qgis@9150 c8812cc2-4d05-0410-92ff-de0c093fc19c

/**QgsLogger is a class to print debug/warning/error messages to the console. The advantage of this class over std::cout, std::cerr & co. is that the output can be controlled with environment variables:
|
|
|
|
QGIS_DEBUG is an int describing what debug messages are written to the console. If the debug level of a message is <= QGIS_DEBUG, the message is written to the console. It the variable QGIS_DEBUG is not defined, it defaults to 1 for debug mode and to 0 for release mode
|
|
|
|
QGIS_DEBUG_FILE may contain a file name. Only the messages from this file are printed (provided they have the right debuglevel). If QGIS_DEBUG_FILE is not set, messages from all files are printed
