Allow 90° rotation when screen grabbing.

In Zaccarria I've been using the screen mirroring feature to display a player 1 score section of the backglass on my ZeDMD. I would find the coordinates for a particular backglass while in paint shop while working with my screenshot, and DMDext was always capturing the wrong area. After setting up a bunch of tables through trial and error I found what DMDExt is doing wrong. It is supposed to draw the capture rectangle as. "x coordinate, y coordinate (upper left corner) width, height" It has been treating the last variable not as height, but as the y coordinate for the bottom right corner.

I am sure not many people are using the screen mirroring function or this would have been noticed a while ago. It's the only way I can see using a standalone dmd with Zaccarria.

Now my wishlist item would be not to capture sections of the backglass, but to mirror the on screen display which only appears on the playfield monitor. The OSD is rotated 90 degrees the wrong way, so what gets captured is a 4:1 image converted to 1:4. My question is, can it be set up so that if the height is greater than the width, then the displayed image is rotated 90 degrees?
