就是画文字
一、设置字体：gg.Font
二、设置颜色：gg.SetColor
三、输出文字：gg.DrawString x,y,"xxxx"
设置字体和颜色永久有效，若不需要改变，无需重复设置。默认为雅黑，9号，黑色字，无底色。

nText 文本
uFormat 格式化样式
返回用了DT_CALCRECT后不描绘，返回文字高度（像素）

常用：DT_CENTER Or DT_VCENTER Or DT_SINGLELINE
DT_BOTTOM             将文本对齐到矩形的底部。该值仅与DT_SINGLELINE值一起使用。
DT_LEFT                   将文本对准左侧。(默认)
DT_RIGHT                  将文本对齐到右侧。
DT_TOP                     将文本对齐到矩形的顶部。(默认)
DT_CENTER              在矩形中居中文字。
DT_VCENTER            纵向中心文本。该值仅与DT\_SINGLELINE值一起使用。
DT_CALCRECT           返回格式化文本的高度，但不绘制文本。
DT_EDITCONTROL   复制多行编辑控件的文本显示特性。具体而言，以与编辑控件相同的方式计算平均字符宽度，并且该函数不显示部分可见的最后一行。
DT_END_ELLIPSIS     如果字符串的末尾不适合矩形，则会被截断，并添加省略号。
DT_HIDEPREFIX         忽略文本中的＆符号（&）前缀字符。
DT_NOPREFIX           关闭前缀字符的处理。
DT_INTERNAL             使用系统字体来计算文本度量。
