194984de2f IMAGE: Remove unused end info structs from PNG code 
Thanks to @dafioram for noticing the problem & sending an initial
patch, and to @wjp for noticing further that the PNG reader did not
even use the end info struct it created either.

Fixes Trac#10217. Closes gh-1028.

4a39f85c1b IMAGE: Implement handling of key color in Indeo transparency 
This should also improve performance by eliminating unnecessary
writes to the output bitmap for opaque pixels and by simplifying
the rendering loop.

dde259f068 COMMON: Remove BitStream base class to allow inlining calls 
All users of BitStream were in fact using a specific, hardcoded variant,
so we can hardcode that variant, removing the need for virtual calls,
and enabling inlining.

This gives Indeo3 the same behavior as other codecs when
encapsulated in a container that provides bit depth information
(e.g. AVI).
