No you didn't write that code. I did, and it was committed to the metageta repo back in March 2010 - https://code.google.com/p/metageta/source/browse/branches/walkdev/lib/geometry.py?spec=svn253&r=253

However, after a cursory Google search I discovered that I gave you that code via email on the gdal-dev mailing list, and when I did, I neglected to include the metageta license text - http://osgeo-org.1560.x6.nabble.com/gdal-dev-Real-and-quot-raster-quot-coordinates-td3749761.html

So I will tell myself off for not including the license text. Bad Luke! You may consider the mapToPixel, pixelToMap and applyGeoTransform functions as public domain and do with them as you want.

The invertGeoTransform function is another matter though. You did strip the MIT/X license text out of the invertGeoTransform (was invGeoTransform) function which I ported to python from the GDAL gdaltransformer.cpp C++ source code http://svn.osgeo.org/gdal/trunk/gdal/alg/gdaltransformer.cpp

You should include the GDAL copyright notice as required by the MIT/X license, which I have reproduced below:
