Summary: Add support of embedAsCFF property for embedded fonts in the
SWF10 runtime
New Features: Font tag supports embedascff property with boolean value

Release Notes:
Add support for CFF font embedding in the ActionScript3 runtime (Flash
Player 10+). Adobe's Text Layout Framework (TLF) requires fonts to be
embedded as CFF to support all the features of the TLF.
Overview:
You can now set an optional attribute 'embedascff' on the tag (e.g. )
to embed a font, setting the AS3 embedAsCFF option to 'true'. The
default value for embedascff is "false" (the default value within
Flash is 'true'), to be compatible with existing code.
Details:
FontCompiler#compileFont checks for an attribute "embedascff" on the
tag. If the attribute is not found, the default value is set to
"false". SWF9Writer#importFontStyle is called with the value as an
additional argument to the method.
SWF9Writer#importFontStyle passes the embedAsCFF parameter value on to
SWF9Writer#importFont.
SWF9Writer#importFont - which generates the AS3 font embedding code -
has an additional parameter 'String embedAsCFF'. In ObjectWriter - the
abstract base class for SWF9Writer - the signature of importFontStyle
had to be modified to take the additional embedAsCFF parameter.
For all other classes extending ObjectWriter (SWFWriter.java,
DHTMLWriter.java, NullWriter.java ), the method importFontStyle has an
additional parameter embedAsCFF now (value can be ignored).
Tests:
Compile test/tlf/embedascff.lzx using the SWF10 runtime. The font
KentuckyFriedChickenFont.ttf has been embedded two times: With
embedascff set to true and false.
1) Validate that the element does not render CFF fonts
The element in line #152 should not be displayed:
Text with font ChickenCFF
2) Validate that TextFlow (TLF) renders CFF enabled fonts correctly
You will see two poems in a gray box. Both are rendered using an TFL
TextFlow instance. The left one uses the CFF enabled font, so you
should see the KentuckyFriedChickenFont.ttf rendered correctly. The
right box does not render the font correctly, since it has been
embedded with embedAsCFF set to false.
3) Check the generated source code for the [Embed] information
The [Embed] element should show that the font has been embedded two
times, once with embedAsCFF set to true, once set to false.
