/** |

* TrueTypeFont is not called SFntFont because it is not expected |
|
51 |
* to handle all types that may be housed in a such a font file. |
|
52 |
* If additional types are supported later, it may make sense to |
|
53 |
* create an SFnt superclass. Eg to handle sfnt-housed postscript fonts. |
|
54 |
* OpenType fonts are handled by this class, and possibly should be |
|
55 |
* represented by a subclass. |
|
56 |
* An instance stores some information from the font file to faciliate |
|
57 |
* faster access. File size, the table directory and the names of the font |
|
58 |
* are the most important of these. It amounts to approx 400 bytes |
|
59 |
* for a typical font. Systems with mutiple locales sometimes have up to 400 |
|
60 |
* font files, and an app which loads all font files would need around |
|
61 |
* 160Kbytes. So storing any more info than this would be expensive. |
