#316 fix - passing array of textures to shader

[Aleš Koblížek]

I encountered a problem when passing an array of textures to a shader:

After setting two materials

    node->setMaterialTexture(0, driver->getTexture("./media/wall.bmp"));
    node->setMaterialTexture(1, driver->getTexture("./media/bark_loo.jpg"));

and passing them to the shader

    s32 TextureLayerID[] = {0, 1}; 
    services->setPixelShaderConstant("myTextures[0]", TextureLayerID, 2);

under both indexes is the same texture

uniform sampler2D myTextures[2];
varying vec2 texCoord;

void main (void)
{
    //gl_FragColor = texture2D(myTextures[0], texCoord);
    gl_FragColor = texture2D(myTextures[1], texCoord);
}

Attached patch makes it work. (I am not sure if this is the correct way to achieve this, though.)
