drawBitmap where one pixel equals one pixel
<p>If I draw a bitmap on a view canvas using drawBitmap(), the images will be resampled so that 1 pixel in the image will be 1 dip on the screen. On a device I have with high pixel density, that means each image pixel is spread across 1.5 screen pixels, degrading the image.  Handy in general, but in some cases I want to carefully select the images I want to draw, then draw them explicitly at their native size, so they won't degrade.  How do I do this?</p>
