Comment(by dzwarg):

 Replying to [comment:7 pracine]:
 > David, So I guess the conclusion to this is that we might want a
 ST_PixelSize function (maybe more a set of ST_PixelSizeX and ST_PixelSizeY
 or even better ST_PixelWidth and ST_PixelHeight), maybe a ST_Rotation and
 certainly a ST_SetRotation.

 ST_PixelHeight, ST_PixelWidth and ST_Rotation.

 Agreed!  I created #928 for ST_PixelWidth, #929 for ST_PixelHeight.  How
 would ST_Rotation handle two different rotations (like when a pixel is
 diamond-shaped)?
