New issue 162 by ccanepacc: black window when resize after certain
transitions
http://code.google.com/p/los-cocos/issues/detail?id=162

at first look seems related to grid transitions, but that is not sure.

Attached bugdemo test_sprite_issue_162.py, punt in the test directory so it
can grab the needed resources.

When using a transition with grid, after the transition ends a resize will
show a black window.

The defect only shows when director.init is called with do_not_scale=True

The problem is in the interaction director.set_projection with
grid.GridBase._set_active(bool):

+ when the grid goes inactive, it attempts to restore the projection and
modelview matrices calling director.set_projection

+ but the correct matrices to use depends on do_not_scale

+ set_projection don't cares about the do_not_scale value, it acts
always as if do_not_scale == False

The handling of director.on_resize suggest to make director.set_projection
a placeholder, and when setting director.on_resize at the director.init
method assing the correct set projection variant.

Thats what I will try first.

tried, it works. Fixed in trunk r1209

autotest snapcompare tells the scripts in test don't change rendering.

Note: this also solves a problem commented on list: after a grid
transition, text and sprites with sharp borders can be slightly blurred
