GLES2.0 spec allows parts of wide lines and points to be drawn even if their center is outside the viewport. Therefore 0x2000 in PLBU_CMD_PRIMITIVE_SETUP has to be set for points. This is already our default setting as it seems to have no negative effect when this bit is always set. Points work as expected but lines don't. It's hard to RE it, because the affected deqp tests also fail with the blob. To respect this behaviour for lines and solve another 2 tests, we need to do a workaround and temporarily extend the viewport by half of the line width. The scissor rectangle is still equal with the initial viewport.
