[X11] Is it possible to upscale the screen without slowing down framerate? #60

It seems that NP2's window looks a little small on my laptop with 1366x768 resolution when window resolution is 640x400, and it seems that things will get worse on a 1920x1080 monitor with the text indistinguishable. When I tried other resolutions like 1280x800 from Screen->Size, the framerate drops dramatically with the background music slows down as well.

(XNP2's main window is not able to resize. And fullscreen option is not work correctly. I'll try to fix them.)

I should to use SDL graphics buffer. I hope SDL works with effective hardware acceleration.

Maybe OpenGL could be used to achieve it. It seems that DOSBox uses it for scaling the screen without slowing down framerate.

Thank you for the information.

Although SDL has more versatility, OpenGL seems to be useful because it is fast. I can not get it right away, but I will refer this info.
