Subject: [PATCH] constraints: Fix titlebars going off the bottom
|
|
|
c70ea2 |
|
|
|
c70ea2 |
The "current" rect includes the frame, so in order to keep the
|
|
|
c70ea2 |
titlebar on screen, window movement must be restricted to at
|
|
|
c70ea2 |
most (height - titlebar_height) past the work area bottom.
