opengl can now compile with ubo buffer objects similar to cbuffers on dx side.
cleaned double up of data from both sides, gfxhandles only need to use the desc info instead of holding onto its own.
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.
Incorrect cmake directory was messing up reading from zips
STB was failing to read from zips, it was failing to get the file info, something we were using as an early out, now if that files on the filepath, we use the memory read instead since stream needs to be a success to get to that point.
Reverted back to a 2d array since when the const buffer changes are made to the shaders they will be completely swapped out for a 1d array with a max size of 16 for the program, id3d11buffers will be shared across shaders apart from object buffers. We still need to decide on a structure to get everything setup so to keep functionality a max of 2 buffers per stage with 1 buffer as a padding so we can start coding constant buffers right away
need to reverse the bitshift on shaderstages so we get values between 0-5, need to also revert the mBoundConstVec back to a 2dimensional array so that the binding point can be dynamic as well.
Added multiple descriptions to handles.
While maps are very efficient and match data very quickly due to hashing and what not, they are tricky memory wise, we cant clear them if they are only made up of structs and enums. Need to explore other methods for doing this. Original system had a sub buffer system with a check based on whether the handle was marked vertex/pixel. With 6 stages possible now we need to think of a more effective method. Since shaderstage is now a bit flag maybe some sort of streaming setup could be used to write without a loop.
