Changes 6.9.72 -> 6.9.74:
-  GUI: Made it possible to configure all label
colors. Before this, it was hardcoded to light
gray. -  Sequencer: Made it possible to configure the
editor seqtrack header backgound color
separately. Before, it just used the "Sequencer
background" color. -  Sampler instrument: Made the crossfade slider
exponential so that it'll be possible to set
accurate small values. -  Sequencer: Paint name of current editor seqblock
in white color also in the navigator widgets. - GUI: Adjust default colors a little bit.
 -  Editor: Fix assertion reporter popping up when
changing number of tracks in "block properties"
while playing. -  GUI: Paint gradient background color for various
text. -  Editor: Tweak tempo multiplier slider graphics a
little bit. Also make the colors for the slider
configurable. -  Playlist: Use same colors as in the sequencer and
paint a border around current entries instead of
using a different background color. Also paint a
small border around non-current entries. -  Sample instrument/Fluidsynth instrument: Make sure
the sample browser is wide enough to show all text
of normal-sized filenames. - GUI: Make all buttons have the "Buttons" color.
 - GUI: Make group boxes easier to see.
 -  Sampler instrument: Support loop crossfade when
using custom loop start/end points. - Sampler instrument: New effect "Loop window".
 -  Internal: Change main timer interval from 5ms to
15ms. This might lighten up CPU usage a little bit.
