2d text alignment is backwards

[concave-sphere]

Bevy version

0.5

Operating system & version

Debian GNU/Linux "buster"

What you did

Inserted text bundles rendering "<HAlign=Left>" with left-alignment and "<HAlign=Right>" with right-alignment, using the same Transform. Did the same for "VAlign\n=\nTop" and "VAlign\n=\nBottom"

What you expected to happen

The Bevy docs describe left and right alignment as follows:

Left: Leftmost character is immediately to the right of the render position.
Bounds start from the render position and advance rightwards.

(...)

Right: Rightmost character is immediately to the left of the render position.
Bounds start from the render position and advance leftwards.

They describe top and bottom alignment as follows:

Top: Characters/bounds start underneath the render position and progress downwards.

Bottom: Characters/bounds start above the render position and progress upward.

This matches my own expectation based on experience with, e.g, word processors, UI libraries, etc. As such, I would expect to see something like this in the center of the screen:

             VAlign
               =
             Bottom
  <HAlign=Right><HAlign=Left>
             VAlign
               =
              Top

Note that the location of the text should be the opposite of its alignment. That is: since the alignment point is in the center of the screen, right-aligned text (text with its right side aligned to the center) should be to the left of center, while left-aligned text (text with its left side aligned to the center) should be to the right of center.

What actually happened

Layout was exactly the opposite of what I expected:

             VAlign
               =
             Top
  <HAlign=Left><HAlign=Right>
             VAlign
               =
              Bottom
