Cocos2d-x移植WP8时CCScrollView的问题

cocos2d-x 2.2中的CCScrollView和CCTableView存在bug，导致区域裁剪错误

我是这样解决的， 在CCEGLView::setScissorInPoints里，根据不同旋转方向，设置不同参数

void CCEGLView::setScissorInPoints(float x , float y , float w , float h)
{
	switch(m_orientation)
	{
	case DisplayOrientations::Landscape:
		glScissor((GLint)(y * m_fScaleY + m_obViewPortRect.origin.y),
			(GLint)(m_obViewPortRect.size.width - ((x + w) * m_fScaleX + m_obViewPortRect.origin.x)),
			(GLsizei)(h * m_fScaleY),
			(GLsizei)(w * m_fScaleX));
		break;
	case DisplayOrientations::LandscapeFlipped:
		glScissor((GLint)(y * m_fScaleY + m_obViewPortRect.origin.y),
			(GLint)(x * m_fScaleX + m_obViewPortRect.origin.x),
			(GLsizei)(h * m_fScaleY),
			(GLsizei)(w * m_fScaleX));
		break;

	default:
		glScissor((GLint)(x * m_fScaleX + m_obViewPortRect.origin.x),
			(GLint)(y * m_fScaleY + m_obViewPortRect.origin.y),
			(GLsizei)(w * m_fScaleX),
			(GLsizei)(h * m_fScaleY));
	}
}
