setviewportclip
setviewportclip
hello.
in my application, i let setviewportclip() not be excuted.
then windirectx module couldn't draw anymore.
by the way, as i made onsize() excuted each time before drawing, it went well.
what is the functionality of setviewportclip()?

the functionality of exgsdirectxview::setviewportclip is
1. initialize a stencil-buffer
2. clear a z-buffer
3. fills a frame-buffer in accordance with viewport background settings.
if you don't call setviewportclip, directx device may stop render, e.g., because stencil test is turned on, but stencil buffer is not initialized. or because z-buffer is not clean. quite strange to comment out some piece of code and expect that everything will continue to be working
sincerely yours,
george udov
