Subject: windowscodecs: Fix init of LONGLONG variable with a negative value in
TGA decoder.
sizeof() is unsigned and thus -sizeof() too which leads to the signed bit not propagated when converted to LONGLONG.
This bug prevented the footage header to be found which contains the TGA spec 2.0 extension.
