Heavily upgraded the drawing features onboard the OpenMV Cam. We now
have all the basic drawing methods folks expect along with all the
parameters you need. Finally! You can make big text fonts.
* Added line thickness support
* Added shape fills
* Added text scaling
* Added draw arrow.
* Filled in all the board control examples. Everything works except for
DAC.
* Moved test drawing scripts to drawing dir and renamed them and added
comments.
* Filled in all the image filter stuff. There are still some tests that
can be renamed, commented, and added to this folder. But, I will do that
later.
* Fixed motion detection thresholds.
* Fixed LCD script comments.
* Fixed BLE return value.
Tried to emulate Arduino's 11 folders... I'd perfer to have all the
shield scripts in one folder... but, that might not make sense. I don't
really want one script per folder however. So, I might merge some more
stuff in the future. I have a grand idea here that will become evident as
I work though the examples.
Anyway, the current structure is not final. It will be in flux for a
little while.
As for Git History, folder history is the best we're going to get. Git
and GitHub don't seem to deal with moves too well.
