Subject: [PATCH] fix: align folder popup to physical pixels for sharp 1px
 borders
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Apply pixel snapping to FolderGridViewPopup's position (x, y) and
dimensions (width, height) to ensure edges align with physical pixel
boundaries. This fixes blurry/anti-aliased 1px borders at fractional
scaling factors like 125% or 150%.

修复：应用组弹窗物理像素对齐以获得锐利的1px描边

对 FolderGridViewPopup 的位置 (x, y) 和尺寸 (width, height) 应用
物理像素对齐，确保边缘与物理像素边界对齐。这修复了在 125% 或
150% 等非整数缩放比例下 1px 描边模糊/抗锯齿的问题。
