[Python-modules-team] Bug#825165: python3-opengl: Can no longer call OSMesaCreateContext for offscreen OpenGL

[Lawrence D'Oliveiro]

Package: python3-opengl
Version: 3.1.0+dfsg-1
Severity: important

Dear Maintainer,

The following lines work from the interactive prompt in Python 2, but
not in Python 3:

    from OpenGL.platform import osmesa; omp = osmesa.OSMesaPlatform
    omp.OSMesaCreateContext

The last line reports the error “AttributeError: type object 'OSMesaPlatform'
has no attribute 'OSMesaCreateContext'” in Python 3. This function is needed
for creating offscreen OpenGL contexts.

This used to work back when the latest version of Python 3.4. Now I have tried
both 3.4 and 3.5, with the same error.
