allocate W*H*4 bytes (rather than W*H*3), as it turned out that
glGetTexImage() returns that much for the default red/white chequer
texture, which is used when the requested texture couldn't be found.
This could be a bug in the implementation (nvidia/100.14.11/Linux x86)
or be normal for compressed textures (GL_COMPRESSED_RGBA_S3TC_DXT5_EXT).
The OSG developers aren't sure about their sizes either (see comment
in src/osg/Image.cpp, revision 7067: computePixelSizeInBits()).
for the 2x2 RGB red/white chequer texture:
0 1 2 3 4 5 6 7 8 9 a b c d e f
IN: ff0000ffffffffffffff0000 (see src/ssg/ssgLoadTexture)
OUT: f70000ffffff....fffffff70000....
where the positions marked with a dot remained untouched.
