Sebastian Leonhardt 5e91ec1401 Samsung YH820/92x keymap bugfixes
This patch fixes some (mostly small) plugin issues with the "big"
YH-keymap patch (a507b). Only one fix affects the main keymaps
(virtual keyboard "DONE" now exits after long key /release/ instead
of long button /press/).

\subsection{Image Viewer}
This plugin opens image files from the \setting{File Browser} to display them\nopt{lcd_color}{ using Rockbox's greyscale library}. Supported formats are as follows.
\begin{table}
\begin{rbtabular}{.60\textwidth}{lX}%
{\textbf{Format}& \textbf{File-extension(s)}}%
{}{}
BMP & \fname{.bmp} \\
JPEG & \fname{.jpg, .jpe, .jpeg} \\
PNG & \fname{.png} \\
GIF & \fname{.gif} \\
\opt{lcd_color}{
PPM & \fname{.ppm} \\
}
\end{rbtabular}
\end{table}
\opt{large_plugin_buffer}{
\par
\note{
When an audio file is playing the size of the image is limited as
the decoding process needs to share memory with audio tracks. To be able to
view a bigger file you may need to stop playback.}
}

}
\opt{lcd_color}{
\item[Display Options.] From this menu you can force the viewer to render the

\end{description}
\note{
Progressive scan and other unusual JPEG files are not supported, and will
result in various ``unsupported xx'' messages. Processing could also fail if the
image is too big to decode which will be explained by a respective message.
\opt{lcd_color}{
Supported PPM files are both ASCII PPM (P3) and raw PPM (P6).
