* The vesa driver no longer uses VGA programming if the chip does not support VGA compatibility. * The VESA driver now tries to set the DAC to 8 bits per color gun. * In VESA modes, the driver no longer tries to use VGA programming; introduced the new vesa_set_indexed_colors() that is now used for palette programming. This should fix wrong colors of 8 bit BWindowScreen users with VESA on real hardware (emulators usually didn't mind either way). * Note that the app_server needs to maintain a palette per 8 bit screen, as right now, the colors are garbled after a workspace switch. Stefano, are you looking into that already? git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32347 a95241bf-73f2-0310-859d-f6bbb57e9c96
