Mirco MirandaandAlbert Astals Cid 402dfb5de3 psd: Fix alpha blending 
PSD files are saved with as alpha premultiplied. The problem is that alpha refers to white instead of black so it requires transformation formulas. Then, to conver PS premultiplied to QImage premultiplied you have to use the following formula:

* V = Alpha + Vps - Max (C, M, Y, K, R, G, B, Gray, L\* components)
* V = Vps + (Alpha - Max + 1) / 2 (a\*, b\* components)

Where Max is the maximum value depending on the image depth and Vps is the valued read from the file.

Mirco MirandaandAlbert Astals Cid 14742cb502 PCX: Fix reading of the extended palette

Mirco MirandaandAlbert Astals Cid dcab3a06ab raw: LibRaw_QIODevice::read: fixed possible partial reading of an item 
- If the size of an item is greater than 1 byte, it must be ensured that it is not partially read.
- In many readings, LibRAW gives an error if a partial number of items are read so I always try to read everything.
