Blit

[SunGQ1987]

struct BlitState
{
	BlitState(const Frame* _frame)
		: m_frame(_frame)
		, m_item(0)
	{
		m_key.decode(_frame->m_blitKeys[0]);
	}

	bool hasItem(uint16_t _view) const
	{
		return m_item < m_frame->m_numBlitItems
			&& m_key.m_view <= _view
			;
	}

what's mean for the code hasItem? As i see the parameter _view means the actually viewID, while the m_key.m_view is only the remap order for the blit view? Whtat does the '<' means between them ?
