修改SourceGrid字体显示
新的SourceGrid DotNet版本是4.40，主要问题是在实现的时候显示的字体实在不敢恭维。
项目源：http://sourcegrid.codeplex.com/
介绍：http://www.codeproject.com/Articles/3531/SourceGrid-Open-Source-C-Grid-Control
修改两行代码搞定：
SourceGrid\DevAge.Windows.Forms\Drawing\VisualElements\TextGDI.cs
protected override void OnDraw(GraphicsCache graphics, RectangleF area)
{
if (Value == null || Value.Length == 0)
return;
SolidBrush brush;
if (Enabled)
brush = graphics.BrushsCache.GetBrush(ForeColor);
else
brush = graphics.BrushsCache.GetBrush(Color.FromKnownColor(KnownColor.GrayText));
graphics.Graphics.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.HighQuality;
graphics.Graphics.TextRenderingHint = System.Drawing.Text.TextRenderingHint.ClearTypeGridFit;
graphics.Graphics.DrawString(Value, Font, brush, area, StringFormat);
}
强制使用高清的方式实现字体显示。
