will change soon though.

it clears the pending flag for a GLOBject.

duplicate LBC/SC logic into a SC method.

so caller can tell whether shader state was actually
changed. GLVolume (for OpenGL 2.1) updated to use this feature.

schedule a 'create' function (to create a GLObject), as it was never
able to capture the GL context.

values (the master dctx inherits from the one remaining child).

texture changes).

state until image textures are ready to be used. New async.wait function
to help with this.

for this sort of code.

2. FSLEyesFrame: When a view panel is closed, and only one remains, it
is synced to the master display context. This behaviour is better than
before (it remains un-synced) but has issues that need to be
addressed (see comment in code).

to come. Related changes due to props refactoring (props@9bbc539d)

2. Little bugfix in lightbox canvas - was using getLimits instead of getRange.

axis/display space change.

overlay, or bounds, change.

now default perspectives.

applied to overlays loaded on command line.

display bounds with respect to the current cursor location. Also
increased maximum zoom level.

when i use glDrawArrays. Using glDrawElements (with an index array)
fixes it.

coordinate) load. I have absolutely no idea, but off-screen rendering
won't work unless i set vertex coordinates *before* setting texture
coordinates.

with this parent-child DCTX requirement, as otherwise the DisplayOpts
classes will be too complicated/flaky.

running. GLModel has to implement GLObject.ready() method.

to choose ortho/lightbox, or to choose a perspective to load.

so their indices match. FSLEyesFrame has better control over
save/restore layout.
