• Copy of a rectangle with same pixel format with possible source-target rectangle
overlap.
• Copy of a rectangle supporting most XRender compositing operations with these
options:
• Pixel format conversion.
• Repeating pattern source.
• Porter-Duff blending of source with target.
• Source alpha masking.
The following are additional features supported by the X-Windows acceleration:
• X pixmaps can be allocated directly in frame buffer memory.
• EGL swap buffers where the EGL window surface is an X-window.
• X-window can be composited into an X pixmap which can be used directly as any
EGL surface.
