Details - The second patch adds the ability to read and use alpha channel information \
in 32bit bitmaps. The font drawing function is re-used to enable alpha blending. I \
tested it with BMPs created by imagemagick and gimp, it's so far enabled for iconsets \
and skin engine (I don't think it works with resizing, so no support for it in album \
arts).

The first patch adds two APIs, lcd_bmp() and lcd_bmp_part() and is required for the \
second. It'll most probably committed anyway. It simplifies drawing bitmaps that come \
out of read_bmp_fd/_file.

Please give it a test and comment. I attach also 3 iconsets for testing

One or more files have been attached.
