2015-01-27when drawing a transformed bitmap in opengl backend, scale it betterLuboš Luňák
The plain scaling is rather rough, and in fact drawing a scaled bitmap the normal way gives much better results (because OutputDevice pre-scales the bitmap before it's drawn). This one may be a bit slow perhaps, but hopefully nobody there's no code that'd extensively use bitmap drawing with custom transformations (wishful thinking).

2015-01-12opengl scaling can also handle the generic aliasesLuboš Luňák
Was missing from 82bc764bc9, without this opengl scaling wasn't used for these. Change-Id: If853435b12383e799afe2f057c43263b2d2297fa
2014-12-15do not hardcode what specific "generic" bitmap scaling operations useLuboš Luňák
I.e. make it possible for the opengl backend to decide to use a different scaling algorithm. Change-Id: I36e76de071797129c7636b3048c93bc6e5d93aca

2014-11-18vcl: since we share Bitmaps across all GLContexts simplify lifecycle.Michael Meeks
~X11SalVirtualDevice() was destroying X resources referred to by OpenGLSalBitmap's mpContext, which were subsequently accessed by Bitmap::AcquireReadAccess on the floating Bitmap. Better to use the default window's GLContext for all bitmap operations. Change-Id: I9009980e791cff1a1f36d626592d72c7a32efd39

2014-11-12opengl: Check for error at the end of every method that deals with OpenGL.Jan Holesovsky
Otherwise we will get the report of an error much much later, most probably in a totally unrelated part. Change-Id: I33d3c6d01126f5766beb179eeaeb3276a9078226
