[Devel] default glyph size

[Werner LEMBERG]

In step1.html it is written:

  When a new face object is created, its size object defaults to the
  character size of 10 pixels (both horizontally and vertically) for
  scalable formats.

Actually, this is a lie.  Calling FT_Load_Glyph() with FT_LOAD_DEFAULT
fails; for example, TrueType fonts will return error code 0x442
(invalid ppem -- BTW, this is an especially nice error since
tterrors.h is hidden in the `internal' subdirectory, not covered with
a meaningful verbal description).

What do you consider better: Changing the documentation by saying that
you always have to use FT_Set_Char_Size(), or adding default values
for x_ppem and y_ppem?
