679aa6032d
Two changes were made:
- Bind the texture before glTexParameteri
- Set the scaling filter before each wlr_render_texture_with_matrix call
Logging in wlroots allows to check that the scaling filter is properly
set prior to rendering.
Fixes: 6968fb3123 ("add scale_filter output config option")
Closes: https://github.com/swaywm/sway/issues/4798
