Port cubeaddon plugin to use new OpenGL plugin API.
(LP: #1020823)

Since the arrangement of the vertex data assumes quad usage, and GL_QUADS primitives are not available in OpenGL|ES, the option "deform caps" will be nonfunctional in OpenGL|ES builds.

\o/

GREAT JOB! Compiles and works perfectly.

(Had to remove #set (COMPIZ_DISABLE_PLUGIN_CUBEADDON ON) from plugins/CMakeLists.txt completely though.)

Awesome to see long-time Compiz features come back !!!

Ah, thanks. I'll handle that now.

[Sam Spilsbury (smspillaz)]

(A note that we really really really really really really really need to have CI do BUILD_GLES and clang, the fact that reviewers are building code is silly)

[Sam Spilsbury (smspillaz)]

Seems to be the same change from:
