Unfortunately Clay does not currently provide feedback on whether a mouse
click was handled or not.
--- if you want to use images with clay, you should pass a pointer to a
sclay_image to the CLAY macro, like this:
CLAY({
...
.image = { .imageData = &(sclay_image){ .image = img, .sampler = 0 } },
})
Using 0 as a sampler uses the sokol default sampler with linear interpolation.
The image should be created using sg_make_image from sokol_gfx.
--- finally, on application shutdown, call
sclay_shutdown()
