Add debug

[AlainLich]

Hi,
the proposed changes permit the user to select debug information printout. I made a similar
pull request in GLWindow. Only tested in Julia 0.4.

1. selection is performed by
   function setDebugLevels(flagOn::Bool,level::Int)
   2)Level (ORed bit values)

1	add traceback for constructors and related
4	print uniforms
8	print vertices
16	used for GLTypes.GLVertexArray
32	used for postRenderFunctions

Additional selection of the IO stream for debug output could be added. Will keep a separate addDebug branch for improvements (based for now on my own usage.

Hi sorry for being so slow...Have you looked into Lumberjack.jl for logging?
It could probably integrated with a macro and a global switch to completely turn the logging off, and then use lumberjack for the different logging levels.

Hi,

I had not thought about it, I see that it is in the Require list of GLAbstraction, so did you try it?
I will give it a try. For now I am redirecting STDERR to reduce the clutter of "Deprecated messages",
but could use a better stream.

Yes I experimented with it, but then more important things came up...
The branch rebuild is down to zero messages now =)
I hope I can integrate it with GLVisualize in the coming days!
That really would be a big step!

Best,
Simon
