Flags describing how to load a font.
</p><p>
These flags describe how a font is loaded and affect how the
glyphs are drawn. There is no way to change this after the font
has been loaded. If you need to render a font with different
attributes, you have to create multiple FontProviders of the
same font file.

Description of how to load glyphs from a font file.
</p><p>
The attributes control how the glyphs are rendered. Width and
height can be used to specify the desired face size in pixels.
If you are loading a non-scalable font, you shouldn't specify
a font size. Please note that the height value in the
FontDescription doesn't correspond to the height returned by
the font's GetHeight() method.
</p><p>
The index field controls which face is loaded from a font file
that provides a collection of faces. This is rarely needed.

<br><br><a name=DFBSurfacePixelFormat><font color=#D07070 size=+2>DFBSurfacePixelFormat</font>

Pixel format of a surface.
Contains information about the format (see following definition).

Format constants are encoded in the following way (bit 31 - 0):
</p><p>
-hgg:ffff | eeee:dddc | bbbb:bbbb | aaaa:aaaa
</p><p>
a) pixelformat index<br>
b) effective bits per pixel of format<br>
c) alpha channel present<br>
d) bytes per pixel in a row (1/8 fragment, i.e. bits)<br>
e) bytes per pixel in a row (decimal part, i.e. bytes)<br>
