OpenGL OSD/Skinlcarsng Channel Display distortion

CPU rendering works.

This seems to have been introduced with skinlcarsng 0.5.4 and may be a bug in softhddevice opengl handling, which was triggered right now.
I can see drawed text, esp. numbers 0-9 rendered in a triangle from 0|0 to the position of DVB-S2.
Needs investigating the first "bad" commit in skinlcarsng to see whats wrong in openglosd.
There could be a problem with the font atlas because of the 0-9 ordering... At least some Draw***() Command triggers it.

Seems to be a bug in skinlcarsng, see https://www.vdr-portal.de/forum/thread/133468-skin-lcarsng/?postID=1393453#post1393453

Though softhddevice should catch these "illegal" values and at least report warnings....
