Hi,
In `TT_Load_Glyph', there is some code that checks if the sizes have been
set correctly.
/* if FT_LOAD_NO_SCALE is not set, `ttmetrics' must be valid */
> if ( !( load_flags & FT_LOAD_NO_SCALE ) && !size->ttmetrics.valid )
> {
> error = FT_THROW( Invalid_Size_Handle );
> goto Exit;
> }
No similar portion is found in `cff_slot_load'. In fact, the check occurs
quite later in the following line:
> error = decoder_funcs->parse_charstrings( &psdecoder,
> charstring,
> charstring_len );
For OT-SVG glyphs, I want to check if the size has been set earlier than
this (because my checks for OT-SVG glyphs come early too). Are there easy
ways to do that? Since I only care about `x_ppem' and `y_ppem' I can just
simply check for those two values as I do here

If there is a more standard way to do this, please let me know. :)
