Sr1 texturing

I've decided today to upgrade the main texture from 2048x2048 pixels to 4096x4096 pixels. This is due increased memory in recent GPU cards. The standard version will be still delievered with scaled down 2048x2048 texture and 4096x4096 will be optional high res set.

A 32 bit 2048x2048 texture consumes = 2048*2048*32 / 8  = 16 Mbytes
A 32 bit 4096x4096 texture consumes = 4096*4096*32 / 8 =  67 Mbytes

I believe 1 gig GPU setup is rather common nowdays so 4096x4096 texture hogs 1/14 of it which I believe is reasonable for increased locomotive realism in near range.

Today first base colors were drawn, Photoshop layer number staying around 12.
