EMI: Miss Rivers walks through Yannia's chair

[monkeymadness]

This occurs during the classroom scene. Miss Rivers disposes of Mungol's gum. On the way back, she walks through the chair. Could be similar to issue #1050, but maybe not because it is another character.

Version of the game: English version from a jewelcase
OS: Windows 7 64bit
Graphics Card: Intel HD Graphics Driver
Renderer: OpenGL
Version of ResidualVM: 0.3.0gitc5ccf4d

I can confrim this occurs in the SW renderer too, assuming that has any bearing on the issue.
