+The keyword "glyph" is followed by six field describing the area of the image
+used for the glyph:
+
+ Field 1: the index of the glyph
+ Fields 2-3: x and y position of the glyph in the image
+ Fields 4-5: width and height of the glyph
+ Field 6: border zone included in the image
+
+The border zone is used with distance field textures to allow the distance
+field to extend past the actual glyph. If a glyph has a border, the origin
+point in the metrics refers to the glyph's lower left corner. Subtract the
+border width from both coordinates to obtain the correct rendering position
+for the image.
+
+The keyword "kern" is followed by three fields describing kerning between two
+glyphs:
+
+ Field 1: the index of the left-hand glyph
+ Field 2: the index of the right-hand glyph
+ Field 3: kerning distance between the glyphs
