WWLCDPanel has two bitmap data, and the bitmap once drawn is

Fixed not to draw. Reduced the load on the X server. (Improvements related to WWLCDPanel and XDisplay_DrawLCDWindow () of XDisplay.c) (XDisplay_DrawLCDWindow () in XDisplay.c has useless malloc () Improvement is necessary of that) In WWDisplay.c (WWDisplay_DrawScreen ()) of wonx-a 05 and wonx-a 06 As a result of trying both, wonx - a 05 was faster, so wonx - a 05 was better I decided to use it. Version 0.0.7 alpha - from wonx-a07.tar.gz
Significantly modified WWDisplay_DrawScreen () algorithm.

Hiroaki Sakai	95d1135996	WWLCDPanel has two bitmap data, and the bitmap once drawn is Fixed not to draw. Reduced the load on the X server. (Improvements related to WWLCDPanel and XDisplay_DrawLCDWindow () of XDisplay.c) (XDisplay_DrawLCDWindow () in XDisplay.c has useless malloc () Improvement is necessary of that) In WWDisplay.c (WWDisplay_DrawScreen ()) of wonx-a 05 and wonx-a 06 As a result of trying both, wonx - a 05 was faster, so wonx - a 05 was better I decided to use it. Version 0.0.7 alpha - from wonx-a07.tar.gz	2000-10-05 12:00:00 +09:00
Hiroaki Sakai	3547ae13a1	Significantly modified WWDisplay_DrawScreen () algorithm. It did not get much faster. When the X server drawing is a hot spot Since it seems, efforts to reduce drawing amount are necessary. Version 0.0.6 alpha - from wonx-a06.tar.gz	2000-10-04 12:00:00 +09:00
Hiroaki Sakai	0cc1bd45ae	Fix XDisplay_DrawLCDWindow (). I put useless calculations out of the loop. 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	2000-10-03 12:00:00 +09:00
Hiroaki Sakai	aa38e7adab	Improved the display routines in XDisplay.c and rendered somewhat faster. Changed method of storing WWLCDPanel data. (I made 1 byte allocated with 1 pixel as 1 byte with 2 pixels) (For speeding up, thought about future color correspondence (241 colors?)) Added WonxDisplay_Sync (). Reduced wasteful drawing in functions of get type. Implement sprite window function. (Not tested) Implement time related functions. (timer.c) Fix sprite priority. (I modified "Priority is given to younger one") Version 0.0.4 alpha - from wonx-a04.tar.gz	2000-09-30 12:00:00 +09:00
