AltoWildgruber 15d86b617a
Update filter_sharpbilinear_flexible.cpp 
The filter is now heavily optimized for speed.

Update filter_sharpbilinear_flexible.cpp 
I implemented smoothstep to make the filter sharper. It's now as sharp as bicubic, but faster.

Interpolation filters 
I created interpolation filters that can easily be included into the filter dropdown list by registering them in render.cpp and wsnes9x.h. 
- the bicubic filter is gamma-corrected and sharper than the built-in bilinear filter.
- the lanczos-filter provides a really sharp upscale and I implemented a reduction of bold black outlines which are often a side effect of Lanczos.
- the sharp bilinear filter is a fast, gamma-corrected filter that is sharper than the built-in bilinear, but not as sharp as the two other filters I added.

The filters include a wrapper function which makes them easy to include into render.cpp.
