pyglet 1.4.10 - spureous traceback quiting test scripts

[ccanepa]

1. all of test/test_* ends with some trivial exception if quiting with ESC or in the programatic termination done in autotest\recon.py.

The exception does not happen if quiting with the window's close button

problem: this polutes the report generated by recon.py, now all test are marked as having tracebacks.

win7, py3.8, cocos b490c, pyglet 1.4.10

Additionally, between the noise was spotted

proxy run cmdline: ['D:\\dev\\cocos2020\\tools\\autotest\\proxy_snapshots.py', 'test_shader.py', 't 0.1, s, q', 'D:\\dev\\cocos2020\\test\\snp']

Error in sys.excepthook:

Original exception was:

in pure pyglet

• noisy.py does not present this defect
• astraea.py shows same behavior than cocos test_* , and also shows the exception when quiting with keypress over the 'quit' menuitem

The problem does not manifest with py 37

testing for cocos 0.6.8 done with py37

fixed in commit 25b24a10 by

• move the termination code outside of on_draw
• calling director.window.close() instead of pyglet.app.exit()
• special casing related to test_shader and test_pyglet_vb
