Editing WoW:API Texture SetTexCoord

{{widgetmethod}}
Sets the region of a texture drawn by the {{api|Texture|t=w}} widget.

 obj:SetTexCoord(left,right,top,bottom)
 obj:SetTexCoord(ULx,ULy,LLx,LLy,URx,URy,LRx,LRy)

== Parameters ==
=== Arguments ===
:;left, right, top, bottom - number
:: side coordinates; top left corner of the image is (0, 0); bottom right corner is (1, 1).

:;ULx, ULy, LLx, LLy, URx, URy, LRx, LRy - number
:: point coordinates; top left corner of the image is (0, 0); bottom right corner is (1, 1).

=== Returns ===
:none

== Details ==
The function can be used to cut a sub-region out of the texture to display in game.

== Example ==
 texture:SetTexCoord(0, 0.5, 0.5, 1)
Displays the bottom-left quarter of the image.

 local ULx,ULy,LLx,LLy,URx,URy,LRx,LRy = texture:GetTexCoord()
 texture:SetTexCoord(ULx*0.5,ULy,LLx*0.5,LLy,URx,URy,LRx,LRy)
 local w = texture:GetWidth();
 texture:SetWidth(w * 0.5)

Change the "view" of a texture to the right, to one half, while maintaining aspect ratio and scale.

== Notes ==
* the coordinates are normalized, and that the origin is the ''top'' left corner.
* Tested in patch 2.0.6, and the origin is in fact in the top left, and not the bottom left as was previously stated
* Unless you want to do rotations, use the ''(left,right,top,bottom)'' notation.
* The more complex 8-argument form allows for arbitrary affine transformations, and transformations based on previous values.
