while it still remains a good idea to port as many NULL compares and assignments over to nullPtr as feasable, we do still need to sort out how to better support scripted empty, false, and zero assigns for things like objectIDs.
this means we'll need to both fully convert the backend of the parser to support that kind of thing, but also alter most if not all exisiting NULLs. up to and including things like SAFE_DELETE. while that's certainly feasable, given there's aproximatel 400 nullptr assigns/checks prior to this commit, and roughly 1800 of the prior, if it terminates in a script call and not an aip one direct, we'll be dialing that back until such time as fork fully fopcused on converting and resolving any lingering mismatches is completed.
deleteSelection when an output node had multiple connections only the first one was deleted, needed a new function to return a vector of connections that are now looped and deleted at the end of delete selection.
few other minor additions and fixes.
add the extra functions for drawing gui elements
RoundedRectangle:
All draw rect functions now pass through roundedRectangle which uses a shader and can draw borders, and rounds the corners
Draw thick line:
draws a line thicker than 1 pixel, uses a geometry shader to do this
Draw Circle:
Draws a circle with a border parameter.
Adds the ground work for geometry shaders
Expands shaderData and gfxShader to allow for more shader types
note: when building a GFXShader in source you have to call setShaderStageFile with the shaderStage and the filepath for that stage.
Once we add compute shaders this will become more apparent as compute shaders are a stage of their own and do not require vertex and pixel files whereas other shaders sometimes do.
