Architecture: alpha

>Description:
	The TGA console is always initialized to 80x34
chars. Depending on font and resolution, different (bigger) x to y
layouts are possible. Currently only a centered window of 80x34 chars
is used, even if there is much more space.
>How-To-Repeat:
	Set TGA to bigger resolution than 640x480 and see that only
part of the screen is used.
>Fix:
	The 80x34 is simply hardcoded in the source. My patch provides
a way to use the whole screen. Ideally the dimensions (or video mode)
should be selectable with wsconsctl etc..

	Here's a patch:

 I believe that Nathan Williams made this change because on the
 larger screens scrolling ended up being very slow.  I believe that
 the correct strategy to solve this is to use the larger size
 initially but to provide a mechanism by which the size can be
 changed from userland.  This would solve both issues.  I am going
 to look into this over the course of the next few weeks...
