ScummVM needs OpenGL with xBRZ support 

I think that OpenGL with xBRZ support should be added to ScummVM. This would make ScummVM games look a lot nicer without the need of slow scalers.

There's an unofficial ScummVM build with xBRZ support available from the xBRZ author. Perhaps someone should ask the xBRZ author to add official support for xBRZ to ScummVM.

What do you mean by "slow scalers"? I mean, even on my 6 year old rig the scalers impose no frame rate drop, they don't even increase CPU load measurably.

Alien Grey: It would have been useful to include a link to the xBRZ code and patches.

I have searched and found this here:
https://sourceforge.net/projects/xbrz/files/ScummVM/ScummVM_1.9.0%2BxBRZ_Sources.zip.zip/download

This includes the latest xBRZ v1.5 patched into ScummVM v1.9.0.

xBRZ is licensed under GPLv3 so I think we can import this.

I can look at adding this as a Pull Request.

I don't mean that the scalers are actually slow but compared to xBRZ they are. xBRZ is faster than the HQ scalers and gives the same or better image. The HQ scalers in ScummVM gives an fps drop on my Windows 10 X64 device.

I didn't want to add a link because I don't know if this is allowed.

It would be awesome if this could be imported to ScummVM. I think it gives the best result with xBRZ and bilinear filtering disabled. The image looks nice, smooth and still sharp like that. With bilinear filtering enabled it starts to look a bit blur.
