pxCore 1.2

We've made some minor additions to our portable open source framebuffer library, pxCore. Most of these additionals were added to support a video capture library that we'll be posting in the near future. Some of the changes to pxCore include:

* Added the ability to directly blit pxBuffer frame buffer descriptors.
* Added beginNativeDrawing and endNativeDrawing to allow native drawing outside of the paint loop.
* Added an example that demonstrates using platform native drawing methods in conjunction with the portable frame buffer primitives in pxCore.
