duilib模仿实现list ctrl的icon

// hDc HDC句柄
// CPaintManagerUI句柄
// rc 目标画布的大小
// rcPaint 绘制区域
// pStrImage 为源图像的名称，不需提供路径，函数内部会自动加上资源位置的路径，路径为CPaintManagerUI::SetResourcePath设置的路径。
// pStrModify 设置绘制属性，含义为：
// 2、file='aaa.jpg' res='' restype='0' dest='0,0,0,0' source='0,0,0,0' corner='0,0,0,0'
// mask='#FF0000' fade='255' hole='false' xtiled='false' ytiled='false'
// source和dest表示从源图像的source区域贴到目标图像的dest区域，mask表示让某颜色为透明色，例如mask="#FF000000",设置黑色为透明色。
// xtiled,ytiled 设置为true表示横向和纵向的图像不拉伸显示而是平铺显示
// hole 为true表示不绘制中间部分，为某些场合提高性能
bool CRenderEngine::DrawImageString(HDC hDC, CPaintManagerUI* pManager, const RECT& rc, const RECT& rcPaint, LPCTSTR pStrImage, LPCTSTR pStrModify)
{
if ((pManager == NULL) || (hDC == NULL)) return false;
// 1、aaa.jpg
// 2、file='aaa.jpg' res='' restype='0' dest='0,0,0,0' source='0,0,0,0' corner='0,0,0,0'
// mask='#FF0000' fade='255' hole='false' xtiled='false' ytiled='false'

void CRenderEngine::DrawImage(HDC hDC, HBITMAP hBitmap, const RECT& rc, const RECT& rcPaint, const RECT& rcBmpPart, const RECT& rcCorners, bool alphaChannel, BYTE uFade, bool hole, bool xtiled, bool ytiled)
画：image（m_rcItem，m_rcPaint，rcItem，rcBmpPart，rcCorner）
1、CControlUI
m_rcItem：控件在窗口上的坐标（相对于窗口）
m_rcPaint：控件需要重绘区域的坐标（相对于窗口）
2、CRenderEngine
函数DrawImageData，DrawImageString处理完之后得到rcItem, rcBmpPart, rcCorner。
rcItem：图像绘制位置坐标，m_rcItem相对于dest（rcItem.left相对于m_rcItem.left移动，rcItem.right相对于m_rcItem.left移动，rcItem.top相对于m_rcItem.top移动，rcItem.bottom相对于m_rcItem.top移动）移动之后的坐标（相对于窗口）
rcBmpPart：绘制图像的那部分区域
rcCorner：图像距离rcItem四周的距离
函数DrawImage处理rcBmpPart
函数DrawImage绘制（根据rcItem，rcPaint，rcBmpPart，rcCorner，其他属性）
设置image
根据xml设置：
CControlUI* CDialogBuilder::Create调用TImageInfo* CPaintManagerUI::AddImage。
TImageInfo* CPaintManagerUI::AddImage调用TImageInfo* CRenderEngine::LoadImage，并保存到m_mImageHash。
程序中动态设置：
bool CControlUI::DrawImage调用bool CRenderEngine::DrawImageString。
bool CRenderEngine::DrawImageString调用bool DrawImage。
bool DrawImage调用TImageInfo* CPaintManagerUI::GetImageEx。
TImageInfo* CPaintManagerUI::GetImageEx调用TImageInfo* CPaintManagerUI::AddImage。
TImageInfo* CPaintManagerUI::AddImage调用ImageInfo* CRenderEngine::LoadImage，并保存到m_mImageHash。
修改duilib动态设置image数据
CRenderEngine：添加

static bool DrawImageData(HDC hDC, const TImageInfo *data, const RECT& rcItem, const RECT& rcPaint,
