- Add class DrawHelper:
- - Line2D_AA - Creates an emulated AA line using triangles. See Recast/imguiRenderGL::drawPolygon for implementation. Line vertices and colors
- are appended in the specified buffer. No actual drawing is done.
- - Line2D_Pixel - Creates a simple line using LINE primitive topology. Line vertices and colors are appended in the specified buffer.
- - Quad2D
- - QuadBorder2D_AA
- - QuadBorder2D_Pixel
- - Polygon2D
- - PolygonBorder2D_AA
- - PolygonBorder2D_Pixel
- - LineList2D_AA
- - LineList2D_Pixel
- - RoundedRect2D - Also copy from Recast/imguiRenderGL::drawRoundedRect
- - Also 3D equivalents
- - Line, Quad, QuadBorder, Box, BoxBorder
- - Then I also need draw* equivalents of those methods. draw equivalents will also create the buffer and submit the draw call.
- - draw equivalents accept a time for how long to display the element, if 0 it will only be displayed for one frame
- - all elements should be grouped into a common vertex/index buffer (as much as possible)
- - draw methods should combine methods above to make drawing easier. e.g. a transparent box with AA line borders should be easily drawable
