There's a bug in elm_Button.cpp

[wetor]

Button::Button(s32 X, s32 Y, s32 Width, s32 Height, String Content, Color TextColor, Color Color)
about "TextColor" and "Color"

in the constructor:

        this->clr = Color;
        this->ntex = render::RenderText(this->fnt, Content, TextColor); 

and in Button::SetContent(String Content):
this->ntex = render::RenderText(this->fnt, Content, this->clr);
This is an obvious mistake.
