#962 tcpdf could not add huge truetype/opentype files

[Funda Wang]

I use addTTFfont() to convert existing truetype/opentype file into raw format, but it seems that tcpdf could not deal with file with large filesize, such as newly published Adobe Source Han Sans:

The memory limits are imposed by your system and php settings.
Be also sure that the font is in one of the formats accepted by TCPDF.
