Description

Enhance Error Handling in PGraphicsOpenGL

This issue aims to improve error detection and provide more informative error messages to help developers identify and resolve issues more efficiently in the PGraphicsOpenGL class.

Expected Behavior

The enhanced error handling in PGraphicsOpenGL will provide descriptive error messages with information about the context and potential causes, leading to more efficient issue resolution.

Current Behavior

Currently, PGraphicsOpenGL lacks comprehensive error handling, which can lead to unexpected behavior and crashes in certain scenarios. Users often encounter issues without clear error messages.

Steps to Reproduce

1. Use Processing with a project that relies on the PGraphicsOpenGL renderer.
2. Encounter an issue, such as rendering errors or crashes.
3. Attempt to identify the cause of the issue, but the error messages are not informative.

Possible Causes / Solutions

The following changes are proposed to enhance error handling in PGraphicsOpenGL:

1. Implement thorough error checks at critical points in the PGraphicsOpenGL codebase.
2. Provide descriptive error messages with information about the context and potential causes.
3. Ensure that errors are logged appropriately for debugging purposes.

These changes will contribute to a more robust and reliable rendering system in Processing, especially for projects utilizing the PGraphicsOpenGL renderer.
