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 } }

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.
