- display.gui-scale is now a number: 0 (auto) or 0.5..4 in 0.5 steps
- explicit scale is no longer limited by window size (tiled windows);
only an open menu page is shrunk to fit the window
- snap Batch2D vertices to pixels on fractional scale (fixes dots above text)
- pass app to settings_common via options (not visible inside modules)
- gui.get_scale() returns a number
- move create_trackbar_setting/update_trackbar_label/create_checkbox from
settings_audio/display/graphics pages to core:settings_common module
- GUI scale trackbar shows the really applied scale, e.g. '3 (effective 2)'
- add gui.get_scale(), gui.get_max_scale(), gui.get_cursor_pos() (UI units);
document that input.get_mouse_pos() returns window pixels
- InventoryView default color is defined once (InventoryView::DEFAULT_COLOR)
instead of duplicated literals; 'color' attribute still overrides it
Manual GUI scale is now limited so that UI is never smaller than
640x480 units (as in other games), otherwise menus did not fit the
window at scale 3-4 in small windows. The unsupported en dash in the
setting tooltip is replaced with a hyphen.
GUI scale (#737):
- add display.gui-scale setting (0 - auto, 1..4 - fixed integer scale)
- auto mode picks the largest scale keeping at least 640x480 UI units
- apply scale in GUI (root size, camera, cursor, tooltips, scissors)
- HUD layout and ModelViewer use scaled coordinates
- add GUI Scale trackbar to display settings
Volume contrast (#399):
- add audio.volume-contrast setting (100% - unchanged sounds,
0% - loud sounds are lowered to the level of quiet ones)
- loudness (RMS) of a sound is calculated once and cached
- add trackbar to audio settings and reset page
