* pixels have the wrong colour - i.e. if they are black,

* > This burring is a problem because (by design) the corners

* of the sliced texture are drawn at native resolution,

* whereas the middle segments are stretched to fit the

* > When *upscaling* the middle segments (i.e. display size
|
|
* greater than texture size), the visible effects of this
|
|
* are mostly imperceptible.
|
|
* > When *downscaling* them, however, the interpolation effects
|
|
* completely dominate the output image - creating an ugly
|
|
* transition between the corners and middle parts.
|
|
* > Since this is a property of hardware rendering, it is not
|
|
* practical to fix this 'properly'...
|
|
* > However: An effective workaround is to force downscaling of
|
|
* the entire texture (including corners) whenever the
|
|
* requested display size is less than the texture dimensions.
