Window flashes on screen

[MikeTheWatchGuy]

When a form is opened, a flash of the window is seen at the default window location. A window flashes on the screen momentarily before user's form window is shown. Then the user's window is shown in the center of the screen.

What's causing this is that in order to determine the size of the form and thus get it perfectly centered on the screen, the form has to be rendered on the screen.

A fix could be to not center windows and allow the system to place them. Or, place them so that the upper left corner is centered.

This does not happen when users specify their own window locations.

Made a new setting in SetOptions. You can now change the default location of all windows from centered on screen to any (x,y) location.

Found a solution! Will be released to GitHub soon and eventually roll into version 2.9!

The fix was to set the alpha channel to 0 while moving the window and restoring it to 255 once the move is complete.

Released 2.9 with the fix.
