fix for [#11597] 2.46R5 and probably problem of all 2.46Rx - UNPREDICTED DRAW sculpt brush

Browse Source 
front and back face test was reversed. This problem still shows up when sculpting from the inside of a mesh, but this 
cant be worked around unless its know which faces are visible or not. (tried some different workarounds but this 
seems acceptable)
