Last pixel of drawn line (under cursor) is not represented in preview, giving the impression that line will be shorter

Pixelorama version: v0.11.3-stable

OS/device including version:
Linux Ubuntu 22.04

Issue description:
When drawing a line, the last pixel preview (a square frame) that will be drawn under the cursor is not represented, giving the impression that the last pixel will not be drawn.

Above, see how the crosshair has no pixel under it, but a pixel will be drawn there indeed.

This gives the impression that the line will be shorter and makes the user want to move the crosshair just a little farther, causing them to draw an extra unwanted pixel.

Steps to reproduce:

1. Select line tool as primary
2. Hold primary mouse button from a pixel to another
