FS#235 - Segmentation fault with animation of large image
Hopefully platform specific, other ports are welcome to check their scaling code.
Reported originally in p.beta-test (28 january 2012) by Cousin Ricky (email dropped)
Symptom: crash on start of second frame rendering
Environment: Unix, with display of rendered picture, rendered picture does not fit at 1:1 on the display
Demo (adjust the H/W to your setting to get them larger, both or any of them):
global_settings { assumed_gamma 1 }
light_source { <-1, 1, -1> * 1000, rgb 1 }
sphere { 2.5 * z, 1 pigment { red 1 } }

Reason for closing: Fixed
Additional comments about closing:
Tested with 3.7RC6 official code: issue does not happen anymore.
Issue due to m_PxCount not being reallocated on TakeOver, needed only when display is scaled.
Fixed with #5604
Code review of patch is welcome.
