371c86bf3f
Requires addition of viewports and alternate framebuffers to greylib which are essentially similar to the core implementation except that the framebuffer can be any size and relationship to a viewport. Drawing is always fully clipped to the intersecting area. Adapt oscilloscope.c to the API change. FFT will use the new features (later update). Get rid of silly and wrong lcd_bmp_part use in OSD. Remove it from plugin API (must be made incompatible now). Change-Id: Iafa5e2174148fb8ad11db6b9d4add0dcabc5c563

|

* which is actually called, making code nicer to read and maintain.
|
|
*
|
|
* Unbuffered routines revert to standard rb->lcd_XXXX funtions on color
|
|
* targets. On color, mylcd_ub_update_XXXX refer to the proper update

* functions, otherwise they are no-ops.
|

|
|
* lib/playergfx.h or lib/grey.h should be included before including this
