code for scr_consize a bit. I also made it work in software targets. If you set scr_consize outside the range of .2 to .9 it now assumes you're an idiot and ignores your setting, using the appropriate boundary value. A note about gl_conalpha for GL targets. It now works up to a consize of .9 rather than working just upto 2/3 of the screen. Works just as it did before. The only reason it matters is that the boundary for scr_consize does not apply to the decision of whether or not to use alpha--only to how big to make the console. That means if you set scr_consize to .91 or something it won't be bigger but you'll lose alpha. Don't even try to report that as a bug---I will tell you simply Don't Do That(TM).
