Fix XDisplay_DrawLCDWindow (). I put useless calculations out of the loop.

Browse Source 
Fix WWDisplay_DrawScreen ().  I put useless calculations out of the loop.

After examining the hotspot, the drawing part of X (XDisplay_DrawLCDWindow () in XDisplay.c
Loop part) became a hot spot, so arrange the array for each pixel
I made it and raised drawing speed.

Version 0.0.5 alpha - from wonx-a05.tar.gz
