x, y
Set (in pixels) the window position (the top left corner).
x,
y can be negative (meaning that the window top
left corner is outside the visible screen), but must be in the
range [-screen, +screen], otherwise an error is shown.
Example: <window ... x="10" y="10"/> (default)
(defined in GAMGI_GTK_WINDOW_ORIGIN_X and GAMGI_GTK_WINDOW_ORIGIN_Y)
Allowed values: -screen_width < x < screen_width,
-screen_height < y < screen_height (optional, coupled)
width, height
Set (in pixels) the window dimensions.
width,
height must be between
the minimum window dimensions and two times the screen size, otherwise an error is shown.
Example: <window ... width="750" height="550"/> (default)
(defined in GAMGI_GTK_WINDOW_WIDTH and GAMGI_GTK_WINDOW_HEIGHT)
Allowed values: GAMGI_GTK_WINDOW_WIDTH_MIN < x < 2 * screen_width,
GAMGI_GTK_WINDOW_HEIGHT_MIN < y < 2 * screen_height (optional, coupled)
