Hello,

I have some problems with resizing in my program (I use it very hard) so I try to understand how it works and have one question.

You have CXTResizeRect, it is just a cover around XT_RESIZERECT structure. All members of this structure is XT_RESIZE type. XT_RESIZE is a typedef for double. WHY? Why you use doubles to  store window rect coordinates? I look to all your code and do not find any places which use this rect members as doubles. I change this typedef to int ("typedef int XT_RESIZE") and nothing changes in library work but library became a little bit smaller and resizing works really faster (it very visibly at busy PC with "Display window content while resizing" Windows options enabled).
