in a generalized form.
The third parameter (int page) indicates wether we will be loading a certain page
in the bitmap or if we will load the default one. This parameter is only used if
the plugin supports multi-paged bitmaps, e.g. cabinet bitmaps that contain a series
of images or pages. If the plugin does support multi-paging, the page parameter
can contain either a number higher or equal to 0 to load a certain page, or -1 to
load the default page. If the plugin does not support multi-paging,
the page parameter is always -1.
The fourth parameter (int flags) manipulates the load function to load a bitmap
in a certain way. Every plugin has a different flag parameter with different meanings.
The last parameter (void *data) can contain a special data block used when
the file is read multi-paged. Because not every plugin supports multi-paging
not every plugin will use the data parameter and it will be set to NULL.However,
when the plugin does support multi-paging the parameter contains a pointer to a
block of data allocated by the Open function.

Decompression routine for 8 bpp.
rowBytes is the number of bytes each source row would take if it were uncompressed.
This _isn't_ equal to the number of pixels in the row - it seems apple pads the data to a word boundary and then compresses it.
Of course, we have to decompress the excess data and then throw it away.
