In the meantime, here's
another version of my patch.
It's for revision 438, it contains changes from the previous one, and it adds the following:
1. Brush vertices are now rendered in 2D views (modern renderer only).
2. Selection box is rendered as a dashed line.
3. [Fixed] Only 3 bottom resize highlights of selection box were rendered.
4. Selection box font size is now the same as entity name font size.
5. Decimal part of selection/selected brush size is now shown only when it's not 0.
6. Entity name text is now horizontally centered on entity's location.
That's how these 6 look like:
7. Texture Application Form: you can apply textures to selected faces by double-clicking on a texture in both texture lists.
8. You can now select stuff while moving 3D camera using Space+WASD keys.
9. Settings form -> Game Configurations ->Saving: "Map Save Dir" and "Autosave Dir" Browse buttons were missing Click handlers.
10. Make Hollow: "Select wall width" window setting can now be applied using Enter key.
