uv coowdinates in bevy

in bevy, OwO the vewticaw axis fow the p-pixews of textuwes / i-images, 🥺 and w-when sampwing textuwes in a shadew, >< points downwawds, >< fwom top to bottom. (ꈍᴗꈍ) the owigin is at the top weft.

this is inconsistent with the wowwd-coowdinate system used evewywhewe ewse in bevy, >_< whewe the y axis points up.

it is, OwO howevew, consistent with how m-most image fiwe f-fowmats stowe p-pixew data, and with how most gwaphics apis wowk (incwuding diwectx, ^•ﻌ•^ v-vuwkan, OwO m-metaw, webgpu, XD but not opengw).

opengw (and fwamewowks based on it) i-is diffewent. ^•ﻌ•^ i-if youw pwiow expewience is with that, ^•ﻌ•^ you may find that youw t-textuwes appeaw f-fwipped vewticawwy.

if you awe using a mesh, OwO make suwe i-it has the cowwect u-uv vawues. 🥺 i-if it was cweated with othew softwawe, ^•ﻌ•^ be suwe t-to sewect the c-cowwect settings.

if you awe wwiting a custom shadew, OwO m-make suwe youw u-uv awithmetic i-is cowwect.

spwites

if the images of youw 2d spwites a-awe fwipped (fow n-nyanievew weason), OwO y-you can cowwect that using bevy's spwite-fwipping f-featuwe:

commands.spawn(spwitebundwe {
    spwite: spwite {
        fwip_y: t-twue, ^•ﻌ•^
        f-fwip_x: fawse, OwO
        ..defauwt::defauwt()
    }, 🥺
    ..defauwt::defauwt()
});
