v0.7.7

Features

• Crisp text at every zoom — all text (single-line TEXT, MTEXT, dimensions, table cells, block text, tolerances, complex-linetype labels and attributes) is now drawn with a signed-distance-field shader, staying sharp at any zoom level and replacing the old stroke renderer.
• MTEXT background fill, mask and frame — MTEXT can carry an opaque or masked background and a border frame, all editable from the Properties panel.
• Text decorations — underline, overline and strike-through now render on text.
• Clickable command options — command-line options appear as buttons next to the prompt, so they need not be typed. Construction commands are now central: CIRCLE offers 3P / 2P / Ttr / Ttt / Diameter, ELLIPSE offers Arc / Axis, ARC, RECTANGLE and POLYGON likewise, instead of each method being a separate isolated command.
• Plot a model-space window to PDF — pick a rectangular window in model space and export it straight to PDF.
• About in the Manage ribbon — the version / About window now has a discoverable button on the Manage tab.
• Ribbon collapse-mode selector and Start-page recent controls — choose how the ribbon collapses when space runs short, and manage recent files from the Start page.

Fixes

• Paste keeps dimensions — pasted dimensions copy correctly instead of losing their geometry.
• Text colour through blocks — inline \C colour codes survive block colour inheritance.
• Text clipped to xclip — text is clipped to a block's xclip boundary, and a debug-assert crash on block fills is fixed.
• Hatch in PDF / plot output — hatches render correctly in PDF and plot export.
• ZOOM Extents ignores construction lines — XLine and Ray display segments no longer blow up ZOOM Extents.

Performance

• Flicker-free hatches — hatch fills are tessellated once, so panning and orbiting no longer flicker.
• Cached text — text vertices are cached across frames instead of being rebuilt every frame.
