Nona GPU not working anymore

[Kornel Benko]

Ubuntu 14.04, 64 bit, default branch.
Graphic card: NVIDIA, Geforce GTX 750, OpenGL/ES-Version 4.5.0 NVIDIA 346.47

The last versions of nona seem to be not working anymore.
There is no crash and no error message. Nona simply hangs.

Using without '-g' parameter works.
I suspect the

Use own code for initialization of GLContext (Windows and Linux)

This should prevent a popup window, as opened by freeglut.
This removes the dependencies on glut/freeglut.
On MacOS there is still glut/freeglut used.

It was not nice with the popup window, but at least it worked.

Suspect or tested that not another changeset is the culprit?
(I tested this code with 2 different graphic cards on my side and also Terry did a test on Linux and on all systems this changeset worked on all our tested systems.)

The order for testing would be:
0beb67edf587
db1a6c64cf17
a6ad9e9ec0d2
35c1d9d96f3d5
 
until you get the hang.

When it hangs, does it print something or remain the console empty?
When the console shows something, than the debug output of "nona -g -d .." would be helpful and also the output of glewinfo.

It was not nice with the popup window, but at least it worked.

With this attitude we can leave the code as it is and don't need to do anything more.

There are more reports about bugs/crashes in nona-gpu. There are less reports about nona-gpu working.

I start with current nona:
#nona -g -d -o xa dsc_4210-1.pto
nona: using graphics card: NVIDIA Corporation GeForce GTX 750 Ti/PCIe/SSE2
destStart=[62, 1141]
destEnd=[4878, 4441]

srcSize=[(4928, 3264)]
srcBuffer=0x7f82a18c0010
srcAlphaBuffer=0
destBuffer=0x7f829eb47010

warparound=0

Here it hangs. Ctrl-C stops the process.

Test with 0beb67edf587: works
db1a6c64cf17: works
a6ad9e9ec0d2: hang
