    Guess it looks a little better with normal boldness font.
    Can probably have a lot of fonts this size... Only using 192 out of 8k rows and can probably but three or four fonts on a row if needed....
    Loading from uSD to PSRAM goes fast.

    One kind of unfortunate thing is that the special Microsoft Cleartype thing that adds a bit of red to the left and blue to the right gets mostly lost when going from 24 to 16 bpp.
    Some of the red is still there, but blue is all gone. Probably should not have used Cleartype... Have to see how it looks without...

    Hard to get font perfect... Think need to switch Windows to 16bpp to capture best font...
    Actually, used Photoshop to save as 16bpp and blue is still there.
    Guess just really hard to see on Monitor in actual size...

    Added a bitblt command to the PSRAM driver interface.
    Now, instead of taking at least 48 horizontal blanks to draw a character in this font, only takes 6 blanks.
    But, this means that font characters width and height now have to be integer multiples of 4...

    Think I'm going to redo the form title so it can be text with font instead of an image of text...

    Made this font for the title. Looks OK.
