vp9_spatial_svc_encoder produces only frames of original resolution

[GoogleCodeExporter]

What is the expected behavior? What do you see instead?
Wasn't able to obtain stream with spatial scalability using current code 
snapshot. All the frames in a superframe have original resolution.

What version are you using? On what operating system?
Git revision 80e729f6018d9af2733bc45d91442391484a202b
MSVS 2013 x64, Windows 8.1

Can you reproduce using the vpxdec or vpxenc tools? What command line are
you using?
vp9_spatial_svc_encoder.exe -f 10 -p 2 --pass=1 --fpf=first_pass_stats.txt -sl 
5 -tl 1 -t 1/60 -b 9000 -w 1920 -h 1080 --lag-in-frames=25 
BQTerrace_1920x1080_60.yuv bqterrace_spatial.vp9
vp9_spatial_svc_encoder.exe -f 10 -p 2 --pass=2 --fpf=first_pass_stats.txt -sl 
5 -tl 1 -t 1/60 -b 9000 -w 1920 -h 1080 --lag-in-frames=25 
BQTerrace_1920x1080_60.yuv bqterrace_spatial.vp9

Please provide any additional information below.
After commenting vp9_change_config(cpi, &cpi->oxcf) call at line 389 of 
vp9_svc_layercontext.c was able to get layers of different resolution. Hope it 
will help to reproduce and localize the problem.
