frb-copy

Description

This program tests texture copying from the frame buffer. There is a capture window on the screen; the image inside the window is copied into the texture buffer. The copied texture is mapped on a panel by the next frame. Changing the size of the capture window and texture format is possible. Two options for the texture copy API (mipmap filter and clear) can be also controlled.
