Bug#897668: [breeze-cursor] Severe Visibility Issue

[Lumin <cdluminate@gmail.com>]

Package: breeze-cursor-theme
Version: 4:5.12.4-1
Severity: important

Dear maintainer,

I'm setting severity to important because the visibility of a cursor
theme is really important.

The problematic cursor is the cross cursor of Breeze and Breeze_Snow,
which are located at the svg files in source tree:

  ./cursors/Breeze_Snow/src/cursors.svg
  ./cursors/Breeze/src/cursors.svg

They look good, but when we actually use the cross cursor in a
low-contrast background it is definitely a pain to find the location of
cursor on the screen.

For example, my cursor theme is Breeze. When I'm taking a screenshot
with flameshot, the whole screen is shadowed, according to source code,
the cursor will be set to the cross. However, unlike other breeze cursors
which are padded with a white margin, the cross cursor is padded with
nothing. In this case the cursor has a very low contrast to the
background hence very hard to caught by eyes.

Similarly, I checked Breeze_Snow. And I guess the cross cursor will also
be hard to find when the background is basically grey or white.

I suggest a fix with high-contrast margin added to the cross cursor.

Thanks.
