Refactor duplicated RenderSystem capability initialization

[Copilot]

Closes:

Four RenderSystem implementations (Tiny, GL, GL3Plus, GLES2) contained identical 9-line blocks for capability initialization, each marked with TODO comments about the duplication.

Changes

• Added RenderSystem::initialiseRenderSystemCapabilities() protected helper method encapsulating the common pattern:

  • Create capabilities via createRenderSystemCapabilities()
  • Set mCurrentCapabilities from mRealCapabilities if custom capabilities disabled
  • Fire RenderSystemCapabilitiesCreated event
  • Initialize from capabilities

• Refactored all four implementations to call the helper method

Before:

// TODO: fire this from emulation options, and don't duplicate Real and Current capabilities
mRealCapabilities = createRenderSystemCapabilities();

// use real capabilities if custom capabilities are not available
if (!mUseCustomCapabilities)
    mCurrentCapabilities = mRealCapabilities;

fireEvent("RenderSystemCapabilitiesCreated");

initialiseFromRenderSystemCapabilities(mCurrentCapabilities, win);

After:

initialiseRenderSystemCapabilities(win);

Net: -17 lines, removed 4 TODO markers.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• download.savannah.gnu.org
  • Triggering command: cmake -DCMAKE_BUILD_TYPE=Debug -DOGRE_BUILD_TESTS=OFF -DOGRE_BUILD_RENDERSYSTEM_TINY=TRUE -DOGRE_BUILD_RENDERSYSTEM_GL=TRUE -DOGRE_BUILD_RENDERSYSTEM_GL3PLUS=TRUE -DOGRE_BUILD_RENDERSYSTEM_GLES2=TRUE -DOGRE_BUILD_DEPENDENCIES=TRUE .. (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
