/** (Optional) device sharing the same memory, and used for input

|
clip masks/alpha masks/bitmaps that don't match our exact
|
|
bitmap format.
|
|
|
|
This is to avoid the combinatorical explosion when dealing
|
|
with n bitmap formats, which could be combined with n clip
|
|
masks, alpha masks and bitmap masks (yielding a total of n^4
|
|
combinations). Since each BitmapRenderer is specialized for
|
|
one specific combination of said formats, a lot of duplicate
|
|
code would be generated, most of which probably never
|
|
used. Therefore, only the most common combinations are
|
|
specialized templates, the remainder gets handled by this
|
|
generic renderer (via runtime polymorphism).
