-- SafeArea.rect unit sanity (#810): the iOS build reported the portrait
|
|
-- safe rect in framebuffer PIXELS while love.graphics works in DPI-scaled
|
|
-- units, and the old clamp kept the inflated top inset -- the launcher
|
|
-- started a band down the screen and left the top of it black. A rect
|
|
-- that cannot fit the unit window is converted back to units with
|
|
-- per-axis ratios (the axes can disagree, #208). No pokered cite: the
|
|
-- launcher is port-only chrome.
