FS#12358 - Support for transparency in 32bit Bitmaps
User who did this: Thomas Martitz (kugel.)
Task details edited:
-------
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. I tested in \
                a few sims (e200, h300, h100, mr500) and RaaA so far.
