No idea. I want big improvements in air conditioning/heat pumps and water purification, though. Comment...

Question: I can see item label height (bit.ly/13AWn6z) is somehow tied to mediaitem_font from ColorTheme but I just can't crack how you calculate it. Care to share the secret? And sorry for a sudden flood of questions :)

int texth = abs(colortheme->mediaitem_font.lfHeight)*11/8;
if (laneh < 16) texth-=2;

Question: any idea why when I call _LICE::LICE_DashedLine(pGraphics->GetDrawBitmap(), 474, 120, 511, 120, 2, 2, LICE_RGBA(255,255,255,255));, with valid args/area causes an access violation in _LICE_MakePixelNoClamp? only tried on OSX

Reply on August 5 2013, 7:42pm (edited at August 7 2013, 8:40am):

What's the bitmap size? Can you tell which call in DashedLine() is executing it? Probably an error with the clip logic... (edit: sorted via email, thanks Oli! Fix coming soon in public licereposit) Comment...

Heh yeah but I always use my own crap =) Comment...

Question: Thanks for the answer - I guess it's kinda touchy to expose something like that. Whatever you decide, no hurry here, feature is far from complete :) And not to break the rules and satisfy my curiosity: How do you draw play cursor these days? Google revealed that in far 2006 you used DrawFocusRect.

Reply on August 5 2013, 7:38pm:

It renders it offscreen and BitBlts it... No longer using DrawFocusRect() Comment...

Question: Using BitBlt to transfer some LICE stuff to arrange and everything works great except when playing a project. Play cursor invalidates stuff I passed, but everything else is preserved. Like this: bit.ly/12NbkUy Any suggestion on how to overcome this? Thanks!

Reply on August 3 2013, 4:04pm:

Hmm yeah we'd need a way to hook the drawing process, maybe I should add that. Unsure if it's something we want to really support, though. Comment...

Question: I'd rather have a WDL/resampler LGPL with an exception for static linking. does such decision defeat the purpose of LGPL in the first place?

I'd really want to make sure if someone improves the resampler, we get the changes too... Comment...

Question: have you thought instead of % for cpu usage in REAPER to adapt a unix like style? 0.5 for 50%, 1.0 for 100% (one core) 2.0 for 100% (two cores), etc. do you see any benefit in it? personally i like it a lot better.

As an option, maybe, but meh in general ;) Comment...

Question: hey man, reaper-dev-day is inaccurate. dev days don't match with running time by a factor of 2 days or something; it can get even worst than that. e.g. in 1460 years the offset will be 365 days. Are we going to get a patch for the inevitable? dammit, leap years. :)

Usually just mess around until I get something to work on either side.. I think I'd lean towards PCRE, but not strongly. Comment...

Nope. Sometimes when introduced, but that's rare too. Comment...

Question: what's the idea behind "m_empties" in various places? it looks like that instead of releasing memory you keep track of it and once done then to release everything (!?)
Asked by gio (94.66.64.x) on July 17 2013, 5:16pm
Reply on July 17 2013, 9:02pm:

Well, when you have items that you would otherwise call free() and malloc() (or delete and new) on a lot, such as buffers, it's sometimes preferable to keep them around for reuse rather than having to modify the heap. Comment...

Question: Is there some kind of TODO list for the SWELL linux port, i.e. things that have to be done for a working native linux version of REAPER?
