Current libvgl implementation (4.1-STABLE)

>Description:

The current version of libvgl in 4.1-STABLE does not draw fonts wider than
8 pixels correctly. The code in VGLBitmapPutChar performs some bit
operations that work only with fonts up to 8 pixels in width.

>How-To-Repeat:

This code should draw a full bar near the top left corner of the screen,
but it only draws a pattern. Only the right halves of each character get
drawn, due to the bit handling in VGLBitmapPutChar.

#include <machine/console.h>
#include <vgl.h>

int main (int argc, char *argv[])
{
  VGLInit (SW_CG640x480);
  VGLTextSetFontFile ("blocks.vgl");
  VGLBitmapString (VGLDisplay, 64, 64, "TEST STRING", 
                   7, 0, 1, VGL_DIR_RIGHT);
  sleep (5);
  VGLEnd ();
}

The blocks.vgl is 8194 bytes long, and is made up like this:

0000000 1010 ffff ffff ffff ffff ffff ffff ffff
0000010 ffff ffff ffff ffff ffff ffff ffff ffff
