Description Martin Flöser 2012-05-05 08:25:55 UTC 
Steps to reproduce:
1. Use OpenGL 1 backend
2. Activate e.g. Invert effect

Actual result:
Effect gets loaded without an error message

Expected result:
Effect gets not loaded as it is not supported and an error message is shown.

Reason for incorrect behavior:
Supported methods check for availability of GLSL, while they should test whether GL2 backend is used.

Pushed by graesslin into branch 'KDE/4.8'.

Properly detect effects which need OpenGL 2

Effects that need GLSL require that OpenGL 2 is active.
It does not matter whether the GPU would support it if
OpenGL 2 is not used.
