Request: add a createShader( String [] vertSrc, String [] fragSrc ) function like p5.js has

Created by: scudly

Now that we have multi-line strings, it is practical to include shader code directly in sketches (or even to construct them programmatically) rather than reading from an external file. The current publicly supported and documented loadShader() API only cleanly supports reading shaders from files. Ideally, we would also have a createShader( String[] fragSrc ) that infers the type and provides a vertex shader as the current loadShader() does.

Passing the source as an array of strings seems more general than taking it as a single, multi-line string and is trivial enough to express in code. It also matches the existing PShader constructors.

まず、issueで言及されている、文書化されたloadShader() APIと既存のPShaderコンストラクターを確認します。シェーダーソースの扱いと、vertex shaderのデフォルト値を比較します。sketchが、明示的なvertex/fragment形式と、リクエストで説明されている推論形式の両方について、String[]ソースからシェーダーを構築できるようになれば作業完了です。
