HiDPI support

HiDPI support refers to the issue of displaying raster graphics (fonts, cursors, images) on high-resolution displays.

The issue is that the physical size of a display remains the same while its resolution increases.

Issues

• Raster images (cursors, icons)
• Fonts (defined in pixels rather than points)
• Cursor hot point
• Zoom/Rotate origin
• Snap distance
• Selection distance (the hot area around selectable objects)

Forum threads

• Improve support of high DPI displays
• Custom cursors and high dpi (Windows and MacOS testers needed)
