Font properties (size, lineHeight and base) get changed when importing .fnt file

[przemo20]

Example steps to reproduce:

1. Launch TTG Tools, open the Font Editor and load the font file from the following ZIP file: RockwellExtraBold.zip (this is one of the fonts from Tales from the Borderlands)
2. Right-click in the box with all three textures listed in it and select “Export coordinates”. Save the files as “1.fnt”.
   
3. Right-click in the same box, but this time select “Import coordinates from Bitmap Font Generator (*.fnt типа xml)”. Import the 1.fnt file.

Actual behavior

The font properties now are mixed up. To see that you can either, repeat the step 2 (with the only difference to save the file as something different, like “2.fnt”) and compare the files (you will see that size and lineHeight got changed from 81 to 100 and base is now 81 instead of 100), or saving the new font file and trying both (unmodified and modified) in the game.
