Run the feature deprecation list on page 2 of the GLSL 1.30 spec backwards:

• #version 130 -> #version 120
• in -> attribute
• out -> varying
• Remove fragColor declaration, replace fragColor usage with gl_FragColor

Vertex shader:

#version 120
uniform mat4 mvpMatrix;
attribute vec4 vertex;
attribute vec2 textureCoordinate;
varying vec2 varyingTextureCoordinate;
void main(void)
{
    varyingTextureCoordinate = textureCoordinate;
    gl_Position = mvpMatrix * vertex;
}

Fragment shader:

#version 120
uniform sampler2D texture;
varying vec2 varyingTextureCoordinate;
void main(void)
{
    gl_FragColor = texture2D(texture, varyingTextureCoordinate);
}
