Details:

I've heard a discussion about this on mailing list:
http://lists.gnu.org/archive/html/gnash-dev/2012-11/msg00005.html

It seems that Microsoft Windows *do generate* the italic/bold/bold-italic font
style automagically from plain face.
For example: http://www.freeimagehosting.net/newuploads/hmcpe.png
Microsoft Sans Serif (for both bold and italic) and Tahoma
(for italic) relied on this capability.


I've created flash file that's likely to expose the problem,
by creating text fields that tries to use plain/bold/italic/bold+italic face
from a modified font that have only 'plain' (no bold/italic/bold+italic)
face.

I used BitStream Vera Sans Mono 1.10 with font name modified to "Gnash
FontFace Tester Mono" for preventing conflict and substitution. Only plain
face was installed.

This is a correct result from Macromedia Flash Player 7.
(You will notice that bold, italic, bold-italic face were automatically
generated)

This is an image result from Gnash.
(You will see that all text were displayed as plain face)

along with test font and reference screenshots. Also attached here.
