\class HbFrameDrawer
\brief HbFrameDrawer draws frames graphics.
This class is not intended to be derived from.
Frame graphics mean graphics that consist of either 3 or 9 parts that are positioned
and scaled followingly.
A 9-piece frame consists of a 3x3 grid, where the corner parts have a fixed size and
the other parts are scaled.
A 3-piece frame consists of 3 parts tiled either horizontally or vertically. The side
parts preserve their aspect ratio and the center part is scaled to fill the remaining space.
For convenience, frame drawer can also draw the frame with a single graphic.
The frame drawer implements the logic of scaling and positioning the frame parts and
takes care that there are no visible gaps between the frame parts when the whole frame
is painted to the display even if the frame bounding rectangle uses floating point accuracy.
Filenames for 9-piece frame graphics are defined according to the following convention.
- top left <name>_tl.<ext>
- top <name>_t.<ext>
- top right <name>_tr.<ext>
- left <name>_l.<ext>
- center <name>_c.<ext>
- right <name>_r.<ext>
- bottom left <name>_bl.<ext>
- bottom <name>_b.<ext>
- bottom right <name>_br.<ext>
Filenames for 3-piece horizontal frame graphics are defined according to the following convention.
- left <name>_l.<ext>
- center <name>_c.<ext>
- right <name>_r.<ext>
Filenames for 3-piece vertical frame graphics are defined according to the following convention.
- top <name>_t.<ext>
- center <name>_c.<ext>
- bottom <name>_b.<ext>
\note The suffixes (e.g. "_l") in the filenames can be redefined with method
HbFrameDrawer::setFileNameSuffixList().
\note If all of the frame pieces cannot be found, the frame drawer falls back to a single
frame graphics piece with filename <name>.<ext> to draw the frame.
If even that does not exist, nothing is drawn.
See class HbIcon for information of supported icon formats and file locations.
The frame drawer stores the entire generated frame graphics in a pixmap for
improving the speed of the paint operations. Therefore, the frame drawer instance should not
be re-created each time the frame needs to be rendered.
Example of how to create a frame drawer and use it.

/*!
\enum HbFrameDrawer::FrameType
\b Undefined The frame type is undefined. It must be defined before being able to draw the frame.
\b OnePiece The frame consist of a single graphic piece, which is scaled to the frame's bounding rectangle.
\b ThreePiecesHorizontal The frame consists of three graphic pieces that are tiled horizontally.
By default, the side parts preserve their aspect ratio and the center part is scaled to fill the remaining space.
Filenames for 3-piece horizontal frame graphics are defined according to the following.
- left <name>_l.<ext>
- center <name>_c.<ext>
- right <name>_r.<ext>
\b ThreePiecesVertical The frame consists of three graphic pieces that are tiled vertically.
By default, the side parts preserve their aspect ratio and the center part is scaled to fill the remaining space.
Filenames for 3-piece vertical frame graphics are defined according to the following.
- top <name>_t.<ext>
- center <name>_c.<ext>
- bottom <name>_b.<ext>
\b NinePieces The frame consists of a 3x3 grid of graphic pieces, where by default the corner
parts have a fixed size and the other parts are scaled.
