Also fix a type mismatch in dropdown widget (g_text.c) and add
an error check in ALSA audio (s_audio_alsamm.c).

cleanup iemgui dialog form names, replacing dashes with underscores. Fix stray bugs in canvas dialog, and clean up css selector names

stop using "x" for sending iemgui colors-- while it has a precision formatter, it doesn't have a maximum size formatter (and it can't because 64-bit archs need the larger values)

 shows as selected when in a gop.

update open dialog window height/width/font/fontsize for iemguis as they are resized/repositioned with the mouse

further refined legacy mode to match both iemgui and graph-on-parent objects.

second draft of iemgui handles--- still some bugs when switching between canvas gop rect and iemguis

made nbx scaling less wonky. It's still a bit wonky, but maybe that's just a function of the font resizing algo and the fact that width is constrained to character width

egregiously rough draft of g_numbox scaling-- need to work on the character-width x-scaling which is currently screwy

 *added legacy option for iemgui objects. Starting pd-l2ork with -lega…

…cy flag positions iemgui objects in their old, vertically inconsistent locations for the sake of retaining complete backwards compatibility.

*added sys_legacy global for inclusion of other potential legacy breakages that may develop later.

fix "pos" method for [nbx]

*fixed cosmetic regression where highlighting of the number when focusing (and reverting focus) was not consistent due to faulty optimization that has now been removed.

*added ability to have spaces in iemgui properties dialog

change type of scalehandle_new and h_master. Document some structs in g_all_guis.h and change some field sizes.

remove canvas/glist arg in a bunch of recently added iemgui functions, and introduce iemgui_draw_move & iemgui_draw_config

*added selected tag to scalehandles since they should only appear when things are selected (or as is the case with GOP, when nothing else is selected)
*fixed regression in number2 where after dialog it requires complete redraw

Still need to fix the label reselection after it has been added/removed.
*fixed vu meter having bogus scale values when changing the label and some out-of-sync selection issues with the dialog. Needs to be vetted like number2.
