Getting the rendered size of a string
|
||
|
|
|
||
|
|
This function might later on be part of a full rendering-interface for
|
||
|
|
creating actual bitmaps of text.
|
||
|
|
|
||
|
|
This function does NOT attempt to handle line breaks, automatic line breaking,
|
||
|
|
fomatting override tags, vector drawings or anything else to that effect.
|
||
|
|
If you need such functionality, you need to implement it yourself. (For now,
|
||
|
|
at least.)
