7270755488 Ensure interval_timer is initialized from main thread 
This avoids the race condition in interval_timer::init which triggers
thread sanitizer errors.

94d8efb875 Disable read/wrote output when status output is off 
This was the only output that was being printed when m_status_output is
false; since this defaults to true in command-line builds this doesn't
affect them.

d564299635 Make it easier to build Basis encoder as one .cpp 
This is adding a missing #pragma once to bc7enc.h and renaming
ast_interpolate to avoid conflicts with the copy in basisu_uastc_enc
(and also making the color space obvious).

0eb541a118 Implement custom resampling command line args 
This change implements -resample X Y command line support in addition to
-resample_factor, when a more sophisticated algorithm is needed to
compute the desired image size.

For example, these can be used to round the image to a multiple of 4 or
to a power of 2 for improved compatibility with various graphics APIs.

950e452f7d Optimize find_optimal_selector_clusters_for_each_block 
In find_optimal_selector_clusters_for_each_block, a noticeable amount of
time is spent computing color distances for pixels of different clusters.

Because for each pixel we only have 4 colors to compare against, we have
to compute a grand total of 64 unique color deltas; the cluster count,
however, is typically ~200 and we computed 16 deltas for each cluster.

It's thus cheaper to precompute all 64 deltas ahead of time and just add
the right deltas up for each cluster.

This reduces the time to encode a 2Kx2K image with a mip chain in a
single thread with SSE4.1 enabled from 7.8 seconds to 7.3 seconds; the
resulting image is binary identical before/after this change.
