This is a C++11 feature that allows the compiler to check that a virtual
member declaration overrides a base-class member with the same signature.
Also src/blitter/32bpp_anim_sse4.hpp +38 is no longer erroneously marked
as virtual despite being a template.
This is remove per-pixel overheads due to use of the SetPixel virtual
method.
These overheads included:
* expensive virtual method call which prevents inlining
* palette lookup for every pixel
* branch on whether palette animation is enabled on every pixel

-Codechange: added CopyImageToBuffer, which produces a readable buffer for screenshots
-Fix: 32bpp-anim now holds animation on transparent objects to avoid strange graphical effects
-Fix: 32bpp-anim now works correct on mouse-movement (it holds the palette animation correctly)
-Codechange: introduced a hierachy of blitters to avoid a lot of code duplication
Note: this allows much easier adding other types of video-drivers, like OpenGL
