changeset 2789614be547 breaks windows xp

[claudio canepa]

changeset 2789614be547  (2012 08 05) breaks windows xp 32bits

Demoing the bug:

  + hg update -r 2789614be547

  + run noisy.py , --> black screen (no text, no ball visible when pressing space)

  + run astraea.py , --> garbage in the window

  + run label_html.py --> white window

Going to the previous changeset with

hg update -d 2012-8-3

all the scripts works alright

Other info:

gpu ati radeon 6570; defect seen with drivers ati catalyst 11.5,  12.3,  12.4,  12.6

The last changeset working (49cf0fc08fe6) was verified only with 11.5 drivers ( I will retest with others and add a followup if i get different results)

Is it possible that calling SetWindowPos with SWP_SHOWWINDOW does not
properly restore the GL context visibility on some drivers (Ie. ATI)?
If that is true though, should this bug not be seen on "fullscreen"
windows when being set to visible?

I've also seen this behavior on Windows 7 with an Radeon 5770 and
commited a patch that fixes that problem for me (rev e4c909e3af71).
Can you test if the latest tip works for you too?
