API Texture GetTexCoordModifiesRect

Return whether subsequent Texture:SetTexCoord operations also modify the rendering rectangle of a Texture object to maintain texture scaling when the texture coordinates are modified.

enableFlag = MyTexture:GetTexCoordModifiesRect

Returns

 * enableFlag: Boolean:
 * false (default) to stretch/shrink the texture on SetTexCoord calls.
 * true to modify the display rectangle's dimensions instead.
