* fixed 32bpp MMX YUV, made the comments clearer, removed an emms.
* removed all "*vlc" aliases except "gvlc" and "fbvlc". The other sucked.
* new --synchro flag which lets you force which images are decoded.
+ * removed an unused variable in the MMX YUVs.
+ * fixed 32bpp MMX YUV, made the comments clearer, removed an emms.

0.1.99f :
Urgency: Important
Description: Fix 32bpp MMX YUV
The MMX 32bpp YUV function is buggy.
-Status: Todo
+Status: Done 13 Aug 2000 (sam)
Task: 0x11
Difficulty: Hard
* It will also set horizontal and vertical scaling indicators.
