Uploaded some clean cursors I made a while ago with scripts for all resolutions.
The triangle arrows are 16x16 to 128x128 pixels and the rounded arrows 32x32 to 256x256 pixels.
I find these higher resolution better looking. I might redo the others with 32-256 format.

For selecting stuff, use the triangle arrow. When the cursor is in normal state use the Ergonomic arrow.
