Jorge Rodriguez	985ac75251	When doing a perfect po2 nearest neighbor downsample don't allow -0.5 and 0.5 to both contribute to a texel or you'll get a double tap.	2014-07-30 09:27:42 -07:00

Jorge Rodriguez	7ead9a748d	Fix. Ring buffers are a height value.	2014-07-29 23:09:41 -07:00
Jorge Rodriguez	043fa28c11	Same deal with height.	2014-07-29 23:02:56 -07:00
Jorge Rodriguez	ebe0473d8b	Add a test suite to do a bunch of different resizes to find problems. One problem found was an incorrect calculation of texel support how many margin texels needed when downsampling. When downsampling we need to spread out the support of each contributing texel, so to compensate you need more margin texels.	2014-07-29 22:50:06 -07:00
