Description

Bug in HM3.3 (also in previous version).

TComAdaptiveLoopFilter.cpp, setSGUBorderAvailability().
Line 2765:

zRefSU = g_auiRasterToZscan[ rTRefSU+ 1];

should be replaced with

zRefSU = g_auiRasterToZscan[ rTRefSU+ uiWidthSU];

Line 2775:

zRefSU = g_auiRasterToZscan[ rTLSU - uiNumSUInLCUWidth +1];

should be replaced with

zRefSU = g_auiRasterToZscan[ rTLSU - uiNumSUInLCUWidth +uiWidthSU];

These code try to refer to top-right block, but raster-index are wrong.
