Incorrect text rendering in GDI mode

[maa3]

Hello,

Windows 7 SP1
CentBrowser 5.0.1002.354 (32 bit) (Portable), DirectWrite disabled

screenshot for comparison:

   

top = reference rendering (MS Office 2007 Word)
bottom = CentBrowser rendering

as you can see, the CentBrowser renders too dark pixels (maybe incorrect gamma?)
