Copybara import of the project: -- a1297d997d0b3cc624bbd1e704ffb7fbb2c5db9d by Emo Todorov <etodorov@gmail.com>: UI imrovements When OpenGL buffer size is too small to hold entire UI with all sections open, older sections (as determined by latest mouse click) are automatically closed as needed. To test this new functionality, uncomment the test near the top of mjui_resize(). UI items now have userid, which can be used for event handling. It is set through the (new) last field of mjuiDef, called otherint. Sections titles can now have a checkmark - in which case they are rendered differently. Set via mjuiDef.otherint: 0- none (as before), 1- rendering changed but box not shown, 2- box shown. This can be used to label sections of special interest to the application. -- b0405bfb3005586ef1d2656ea9cc43c608225927 by Emo Todorov <etodorov@gmail.com>: more ui improvements Implemented mjPRESERVE state for adding sections and separators, so you don't have to keep track of old states. simulate.cc is now modified to use this new functionality. I also made the separators in the Physics section collapsible. If you don't like it, change them back to state 1. Also added functionality for handling section checkboxes. -- 10f4c49be62a6605a38b7c0c7bfae1629024ba31 by Emo Todorov <etodorov@gmail.com>: even more ui improvements Selection boxes that extend below the current UI height are finally rendered in full. Sections and collapsible separators now have rounded corners. The radius can be controlled from theme spacing. More theme color settings were added. In particular, color gradients can now be disabled (the two end colors are set independently). -- 96c2dc601a25d31c93b21f8e089d349e729e829e by Emo Todorov <etodorov@gmail.com>: final ui improvements Cleaned up the code a bit. Added more control for color gradients. -- c9eddb679f36df3f0745d37e3fa90c4e66ee6b98 by Emo Todorov <etodorov@gmail.com>: bug fix Fixed some rendering bugs in the new functionality.
