Jacob Boerema c8a8d06cd8 plug-ins: move unchanging code out of the loop in dds load_layer 
Optimize dds loading a bit by moving code that doesn't change outside
the loop:
1. The number of bits to be shifted when the source isn't exactly 8 or
16 bits depends on bytes per sample and isn't changing inside the loop.
2. Use rowstride variable to compute width * d->bpp once.
3. The check for rowstride > hdr->pitch_or_linsize doesn't change
inside the loop so move it out.

Inside the loop we only check the DDSD_PITCH flag once and move both
the size check and the fread check inside it.

(C) 2004-2012 Shawn Kirst <skirst@gmail.com>,
with parts (C) 2003 Arne Reuter <homepage@arnereuter.de> where specified.
==========================================

This is a plugin for GIMP version 2.4.x. It allows you to load and save
images in Direct Draw Surface (DDS) format.

Features
==========================================
* Load/Save DDS files using DXT texture compression
* Automatic mipmap generation on save
* Load mipmaps into separate layers
* Load cube map faces and volume map slices into separate layers
* Cube and volume map saving
* Pixel conversion selection for custom formats (RGBA4, R5G6B5, RGB10A2, etc.)
* Load/save DDS files, optionally using DirectX texture compression (DXT)
* Optional automatic mipmap generation when saving
* Load mipmaps into separate layers
* Load cube map faces and volume map slices into separate layers
* Save cube maps and volume maps with automatic mipmap generation support
* Save image with a custom pixel format
* Non-power-of-two image loading and saving support with automatic mipmap generation support
* Compliant with DirectX 10 compressed formats
    

Installation
==========================================
See the file INSTALL for installation instructions
