non_power_of_two_textures

bool gdk::graphics::limits::non_power_of_two_textures = true

whether a texture may be other than a power of two wide and tall with any filter and wrapping

ES 2.0 and WebGL 1 take one only unmipmapped and clamped on both axes, which a webgl1es2_texture made so is allowed whatever this says; anything repeating or mipmapped must be a power of two there.
