Yes I've edited the file /etc/drirc as you said and successfully parsed it with
driconf after adding this lines:
    <device driver="i915">
        <application name="Krita" executable="krita">
             <option name="fragment_shader" value="true" />
             <option name="stub_occlusion_query" value="true" />
        </application>
        <application name="Don't Starve" executable="/home/user/GOG Games/Dont
Starve/start.sh">
             <option name="fragment_shader" value="true" />
             <option name="stub_occlusion_query" value="true" />
        </application>
None of these programs were launched in the right mode, and they still require
support for OpenGL 2.1.

I apologize for not saying at once, I'm not an experienced Linux user, and I
don't know what is in this library and where is it located. But this is what I
get using glxinfo | grep OpenGL command in terminal:
OpenGL vendor string: Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) 945G x86/MMX/SSE2
OpenGL version string: 1.4 Mesa 17.2.0-devel
OpenGL extensions:
OpenGL ES profile version string: OpenGL ES 2.0 Mesa 17.2.0-devel
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 1.0.16
OpenGL ES profile extensions:
