*
* The Type 1 glyph loader uses three distinct objects to build
* scaled and hinted outlines from a charstrings program. These are :
*
* - a glyph builder, T1_Builder, used to store the built outline
*
* - a glyph hinter, T1_Hinter, used to record and apply the stem
* hints
*
* - a charstrings interpreter, T1_Decoder, used to parse the
* Type 1 charstrings stream, manage a stack and call the builder
* and/or hinter depending on the opcodes.
*
* Ideally, a Type 2 glyph loader would only need to have its own
* T2_Decoder object (assuming the hinter is able to manage all
* kinds of hints).
