API Change [GLProfile/GLContext]: Add notion of hardware acceleration in GLProfile.get<Profile>() methods.
We need to distinguish between software and hardware accelerated OpenGL profiles
to allow choosing the proper profiles [default, GL2ES1, GL2ES2, ..]
on platforms where both, software and hardware implementations exist (GL, GLES2, ..).
Where no preference is being requested, hardware acceleration is favored:
GLProfile.getDefault()
GLProfile.getGL2ES1()
GLProfile.getGL2ES2()
Some method signatures needed to change
GLProfile:
getMaxProgrammable(AbstractGraphicsDevice device) ->
getMaxProgrammable(AbstractGraphicsDevice device, boolean favorHardwareRasterizer)
GLProfile adds: isHardwareRasterizer()
Determination whether a hardware acceleration is being used or not
is extended in GLContextImpl by querying the current context's
GL_RENDERER string. If the latter contains 'software' (case insensitive)
it is not hardware accelerated. At least this works w/ newer Mesa3D impl,
where GLX_SLOW_CONFIG is not set!
