* One extra pixel at the left and the right will be needed to absorb
* the pixels that will be touched by filtering by GDI to compensate
* for colour fringing.
* However there seem to be some cases where GDI renders two extra
* pixels to the right, so we add one additional pixel to the right,
* and in the code that copies this to the image cache we test for
* the (rare) cases when this is touched, and if its not reduce the
* stated image width for the blitting loops.
* For fractional metrics :
* One extra pixel at each end to account for sub-pixel positioning used
* when fractional metrics is on in LCD mode.
* The pixel at the left is needed so the blitting loop can index into
* that a byte at a time to more accurately position the glyph.
* The pixel at the right is needed so that when such indexing happens,
* the blitting still can use the same width.
* Consequently the width that is specified for the glyph is one less
* than that of the actual image.
* Note that in the FM case as a consequence we need to adjust the
* position at which GDI renders, and the declared width of the glyph
* See the if (fm) {} cases in the code.
* For the non-FM case, we not only save 3 bytes per row, but this
* prevents apparent glyph overlapping which affects the rendering
* performance of accelerated pipelines since it adds additional
* read-back requirements.
