Implement other scaler

[thotacc]

Hi guys!

Anybody can help me how to implement 1.5x scaler?
In the scaler.cpp there is an implementation but I don't know how to activate it. If i overwrite the Normal2x scaler to Normal1o5x in the graphics.cpp the scummvm crashes,

Please help me!

Thank you very much and sorry for my ugly english!
